1. Pierre Meystre becomes Chief Editor of the Physical Review journals.
I have long been dissatisfied with the editorial practices and quality of the Physical Review journals,
to the extent that I no longer consider submitting papers to them. About a year ago, Meystre published
in Phys. Rev. Lett. (PRL) a self-congratulatory editorial on its editorial and refereeing practices.
After all the trouble I had with them and Phys. Rev. A regarding the Dressel/Jordan affair (see Feb. 9, 2014 entry),
this motivated me to write the following October 18, 2015 letter to PRL Editorial Director Daniel Kulp,
with copies to Meystre and editor Robert Garisto. On hearing of Meystre's ascension to the position of
Chief Editor, I revisited it. I think it is worth reprinting:
Dear Dr. Kulp:
This is motivated by a recent Physical Review Letters (PRL)
editorial of Pierre Meystre on refereeing, which states that
"... the critiques most clearly raised in your responses
[to a survey] address the quality of referee reports,`
followed by the quality of editorial handling.
These are not new. ... "
It goes on to cite a 1970 editorial by Goudsmit which deprecates
such concerns, associating them with paranoia. I disagree with
the 1970 editorial and by extension, with Meystre's. I think that the survey
probably reveals valid concerns which the administration has yet to address.
This letter is to put on record a recent experience of mine
with PRL which provides unusually unequivocal evidence for such concerns.
Full documentation can be found on the "papers" page of my website
www.math.umb.edu/~sp, starting with the August 18, 2012 entry entitled
"Standards of Physical Review Letters".
In very brief outline, PRL had published a Letter which
made mathematical claims for which I had been unable to obtain valid proofs
from the authors. After I sent them counterexamples, they ignored
future correspondence. Since I was unable to resolve the matter informally,
I submitted a "Comment" (LBK1086) to PRL containing the counterexamples.
It took months to convince editor Robert Garisto to send it to
a referee. My impression was that he was acting more as an advocate
for the authors than as an impartial observer trying to get to the root of
a difficult matter. (Unsolicited and inapppriate pronouncements of Garisto
on a personal issue unrelated to the Comment reinforced this impression.)
For example, an early counterexample which was too long for
PRL's 1-page limit but fully worked out in the arXiv was disallowed
solely because its full justification was in the arXiv. However,
a short counterexample which was presented in the 1-page Comment was
initially disallowed solely because the authors claimed to have refuted it
in an arXiv posting. It is understandable that arXiv postings might be
disallowed as evidence, but if so, the same should have applied to the authors.
About a year later, the authors published an attempted proof
in Physical Review A (PRA). It was wrong because the authors had
incorrectly multiplied two matrices (which could be as small as 2x2).
Since the authors still refused to communicate with me, I submitted
a "Comment" to PRA. It was rejected on the basis of two obviously flawed
referee's reports. One report admitted that its author did not understand
the mathematics of the paper under review. The other recommended rejection
on the basis of the referee's elementary mathematical error, an error
which even an editor unfamiliar with the subject matter should have recognized
after I pointed it out. My pleas to submit the referee's report to
a competent mathematician for resolution of this elementary mathematical issue
The authors were aware all along that the matrices had
been incorrectly multiplied, but they explicitly refused to confirm
or deny this. The PRA editor seemed to treat these "stonewall" tactics
as perfecly normal and acceptable.
[The discussion of PRA might seem irrelevant to PRL,
but I include it to illustrate that the treatment of the
submitted "Comments" by the two journals was very similar,
likely fostered by the professional culture of APS.
The PRA case is particularly compelling because the issue
was so clearcut: whether two matrices had been correctly
multiplied. The PRL case was more complicated. In both
cases, blatant "stonewall" tactics of the authors
(e.g., refusal to furnish basic information)
were treated by the editors as perfectly normal and proper.]
Like PRL, PRA appeared to treat the Comment as a mere
nuisance, not to be seriously considered, but to be disposed of
by any available pretext. The authors were granted every benefit
of the doubt, but even my claim that two matrices had been incorrectly
multiplied appeared to be greeted with skepticism.
I appealed the rejection. It took the adjudicator three months to
report that the matrices had in fact been incorrectly multiplied,
which invalidated the authors' claimed proof.
PRA then gave the authors the choice of either submitting
an erratum or having my Comment published. Despite the authors'
continuing refusal to cooperate in resolving a matter that could
have been resolved within days, they were afforded every consideration,
as if PRA regarded their behavior as normal and proper.
They chose to finally submit the Erratum.
I wrote to PRL inquiring if they might similarly ask the
authors about submitting an erratum retracting the false claims
which PRL had published, and in case they refused, consider another
Comment. Editor Garisto flatly refused, citing PRL policy.
If he is correct that PRL policy is so inflexible as to
prohibit PRL's warning readers that previously published claims
have turned out to be false, then the policy should be changed.
If PRL knows to a certainty (as it does in this case)
that a significant published claim is false, then it should correct
the public record.
I will close by returning to the Meystre editorial which
motivated this response. Read in isolation, it seems mainly too vague to
be meaningful. But read in conjunction with its cited 1970 Goudsmit
editorial associating concerns over editorial practices with
paranoia, it conveys a message that the system is pretty good,
and that anyone who thinks otherwise is likely borderline paranoid.
I don't think the system is pretty good. The paper mentioned
above would never have been published had it been properly refereed.
I cannot believe that it was ever read with understanding by any referee,
and I doubt that this is an anomaly.
The enormous resistance to correction of PRL's published false claims
indicates an unprofessional culture of unconcern. I do not know if
you have a realistic chance of changing that. This letter is written
on the off chance that it may actually be read and that you have the
means and desire to make PRL into a journal whose professional standards
are beyond reproach.
There was no reply, but no reply was either required or expected.Sincerely yours,
Professor of Mathematics (retired)
University of Massachusetts at Boston

Of course, I can't help wondering what editorial practices Meystre may foster, given his unconcerned editorial.
But I do not know that he is actually unconcerned, so we can hope for the best. He may have been unaware just
how unprofessional the editorial practices of the Physical Review journals have become. It's not just Phys. Rev. Lett.
and Phys. Rev. A. I also have had experiences with poor editorial practices at Phys. Rev. D. Because of these experiences,
I no longer consider submitting papers to these journals.
2. New paper
I just posted a new paper at arXiv:1610.04607 . entitled
"Quantum measurements need not conserve energy: relation to the Wigner-Araki-Yanase theorem" .
It starts with the trivial but puzzling fact that quantum measurements need not conserve energy (unlike unitary evolution).
This has been known at least since a 1952 paper of Wigner, but I've never seen it discussed
in detail. This seems strange because it seems to me that it poses a foundational problem for quantum mechanics.
The Wigner-Yanase-Wigner (WAY) theorem states that under its hypotheses, a quantum
measurement must conserve energy! Put differently, measurements which do not conserve energy (which are most measurements)
cannot satisfy their hypotheses.
The hypotheses of the WAY theorem seem superficially fairly general, but in view of its strong conclusion, obviously must be quite restrictive.
The paper explores the contradiction and in the process formulates a measurement model a bit more general than the "standard"
model of Von Neumann, along with somewhat stronger versions of the WAY theorem.
The paper reaches no formal conclusion on the origin of the near-contradiction (that general quantum measurements do not conserve
energy but must conserve energy under the seemingly mild hypotheses of the WAY theorem). My personal view is that the "standard"
measurement model of von Neumann (which the WAY theorem assumes) may simply be physically unrealistic.

(a) JPA held the Comment submission P for almost a year before(4) Concern about the difficulty of genuine peer review in physical science reported
rejecting it. They were unable to obtain a referee's report. (By comparison,
DJ was accepted in about a month despite the fact that JPA was well
aware that its main result was disputed.) The only "reason" given for the rejection
was that "this course [rejection] is the most satisfactory [for JPA]".
(b) Meanwhile, JPA furnished a copy of P to Dressel and Jordan , in
response to which they published in JPA the Corrigendum DJcorr.
JPA never sought my opinion of DJcorr; I only found out about
it by accident.
(c) After noticing the incorrect matrix multiplication which invalidated
DJcorr, I submitted to JPA yet another "Comment" pointing it out.
JPA held this one for about six months before rejecting it on the
pretext that its "claim" that DJcorr's proof is incorrect had already
been posted in the arXiv! Indeed, the author of the rejection (an unnamed
member of JPA's Editorial Board) went so far as to say that it was not necessary
for JPA to even consider this claim [that the proof relied in an essential way on
an incorrect multiplication of two matrices]. This may sound so unbelievable
that the reader may want to read the short rejection letter reproduced verbatim
(including unusual formatting) here.
[NOTE added Feb. 25, 2014: In the originally posted version of this entry, the link
just above linked to the wrong document. It linked to the rejection letter for the
Comment P rather than to the rejection for the later Comment on the error of the
Also, perhaps I should have mentioned that the substance of the refusal to even
consider the "claim" that the proof of DJcorr rested on the incorrect multiplication
of two matrices is in the short middle section (delineated with "======")
comprising the Board members report. I included the entire email containing
some distracting boilerplate because I was afraid that if I deleted all but
the short Board member's report, it might seem as if I could have
deleted something important. ]
(d) The authors had also published the main result of DJ as part of a long
paper in Physical Review A (PRA), which was written in a different and
Phys. Rev. A 85, 022123 (2012), arXiv:11100418v2It is generally considered bad form to publish the same result twice,
but perhaps it could be justified in this case because of the different notations.
The proof of the PRA paper contained the same error
[an incorrect matrix multiplication] as DJcorr.
I submitted a similar "Comment" paper to PRA, which initially rejected it
because of two negative referees' reports. Neither of these reports
addressed the issue of the incorrect matrix multiplication! One of the referees
admitted that he did not understand the mathematics of the PRA version of DJ's
proof. The other referee recommended rejection on the basis of an elementary
mathematical error which he made. It was clear from his report that
he didn't understand the mathematics, either.
I appealed the rejection. It took the adjudicator three months to report that
the proof of DJcorr was in fact invalidated because of an incorrect matrix
The adjudicator said that my "Comment" could be published (modulo a few
cosmetic changes), but that it would be better for the authors to submit an
Erratum instead. When I initially submitted the Comment, it was sent to the
authors, who refused to either confirm or deny the error. In case this sounds
almost unbelievable, I stand ready to furnish evidence in the form of the author's
reply which PRA furnished. (Because of the way it was obtained, I don't feel
comfortable putting it on the website, but I will furnish it privately upon serious
inquiry.) After the authors realized that the "Comment" would be published
unless they submitted an Erratum, they agreed. The Erratum has been published,
Phys. Rev. A 88, 039902(E) (2013)
and can be accessed without a subscription at the PRA website here .
(The authors have not posted it in the arXiv, nor as of this writing corrected
the posting arXiv:11100418v2 which contains the error.)
(e) To get back to J. Phys. A, I wondered if their astounding refusal to even
consider the Comment pointing out the error in DJcorr might possibly reflect
not the standards of the journal itself, but instead laziness in evaluating the
"claim" that the proof of DJcorr was invalid because of an incorrect matrix
[I have observed that many physicists dislike carefully reading proofs.
I speculated that it might have been hard to find a referee who would
would rule on the correctness of a proof, for fear of embarassment
should he be wrong. Referees typically prefer pronouncements
so vague as to be impossible to dispute.]
I wondered if the fact that the authors had admitted the error in PRA might
make a difference to JPA. Surely, I thought, the fact that a rival journal
had corrected the error where JPA refused to even consider the matter might
reflect badly on JPA.
So, I wrote to the publisher of JPA in October, 2013 to find out if its decision
not to correct DJcorr's error truly reflected the standards of JPA. The letter is here .
The reply received in December, 2013, makes clear that JPA's refusal to correct
DJcorr does reflect the low standards of JPA:
"Dear Dr Parrott,(3) Final assessment of the standards of the three mainstream journals involved
The Editorial Board and Publishing Staff have given full consideration
to your appeal on your Comment article with reference to our ethical
guidelines and I am writing to tell you that we will not be taking any
As you acknowledge, the authors have made corrections in subsequent
works. Your Comment does not make sufficient advance beyond these
subsequent works to merit publication in the journal. It is not best practice
to correct all historical articles that have been superceded by amended and
corrected works and we therefore must consider this matter closed.
[signed by the Publisher]
I have a few comments on this. First of all, the above letter to JPA was not an "appeal" to
reverse the decision to reject my Comment. It was an appeal "to publish some sort
[emphasis added] of correction to the claims of [DJ's 'General theorem'] and the Corrigendum".
What I had in mind was inducing Dressel and Jordan to themselves correct DJcorr.
That is what PRA did. If DJ refused, then JPA could publish the Comment.
Because the PRA version of DJ's "General theorem" is written in unusual and complicated
notation entirely different from the JPA version, the two may be almost unrecognizable as
essentially the same by many readers. Few readers of DJ and DJcorr will know that
their main result has been retracted in PRA.
At the very least, JPA could add a link to the PRA Erratum in the electronic version of
DJcorr alerting readers that its proof is invalid. If they didn't want to publish the Comment
and also DJ refused to correct DJcorr, they could add an editorial note to the effect that
DJcorr was disputed, and more details could be found in the PRA erratum.
We are talking about a one-sentence notification that readers should not rely on the results of DJ
or DJcorr. Why would the publisher consider this "not best practice"?
It is clear to me that JPA has no interest in correcting erroneous work that they have
in the Dressel/Jordan affair, Physical Review Letters (PRL), Journal of Physics A (JPA),
and Physical Review A (PRA
Standards of Physical Review Letters (PRL):
PRL published the original announcement of the main result of DJ (see above for
reference) with an abbreviated proof in:J. Dressel, S. Agarwal, and A. N. Jordan,This paper contained so many serious mathematical errors that
"Contextual values of observables in quantum measurements",
Phys. Rev. Lett. 104, 240401 (2010), arXiv:0911.4474
to be called DAJ below.
I cannot imagine that the referee(s) could have read it with any
care. The mathematical errors were fundamental, and not of the
nature of the incorrect matrix multiplication of DJcorr. That it
was published does not reflect well on PRL's standards.
[I don't want to make too much of the incorrect matrix multiplication,
which probably could have happened to anyone in a singly authored
paper, though its presence in the doubly authored DJcorr suggests that
one of the authors may not have been pulling his weight. But the serious
mathematical errors in DAJ are of a different nature.
DAJ should never have been published in its present
form. Any competent referee should have caught at least some if its
questionable statements, as I did. ]
In February, 2011, I wrote the authors about the errors and asking about
the sketch of the proof in DAJ of its only nontrivial mathematical claim.
They sent me an expanded proof which was fundamentally wrong. I
replied with my objection, but they never acknowledged it and ignored essentially
all subsequents inquiries about DAJ. Finally, I wrote up my objections in a Comment
paper and submitted it to PRL.
This Comment was not well received by PRL. It took months to persuade
the editor to even send it to a referee. I requested that the referee not be one who
had initially approved DAJ, but they sent it to him anyway. I know this because
his report stated that he had been persuaded to approve DAJ despite misgivings.
He recommended rejection of the Comment on the sole ground that he thought that
it would not be understandable by readers unfamiliar with DAJ.
This was an obvious pretext. Since PRL strictly limits its Comment papers to one page,
it is an obvious impossibility to summarize a complicated paper so that readers
unfamiliar with it could follow all the technical details. Were this requirement uniformly
enforced, PRL could publish almost no Comment papers.
I appealed, and the adjudicator (a Divisional Associate Editor) recommended rejection
on the same grounds. The DAE had the integrity to admit that he did not fully understand
the mathematics of DAJ, and he did not claim that there was any substantive error in the
Although the above and subsequent analysis is critical of PRL, I do want to record a note
of praise. Unlike JPA, PRL and PRA have an established appeal process, and part of
this process is that the DAE serving as adjudicator must sign his name to his report.
This is very important. It distinguishes his review from anonymous referees' reports.
Because the latter are anonymous, referees may suffer little embarassment if their reports
are obviously wrong. For example, the referees who refused to recognize the incorrect
matrix multiplication in DJcorr would probably have taken more care if they knew
that their identities would be revealed.
Years later, after the authors had retracted the result of PRA which had been announced in PRL,
I wrote to PRL asking if they might be interested in exploring with the authors the possibility of
an erratum in PRL.
[ The false PRL claim was much stronger than the PRA claim which the
authors had retracted in their Erratum. The PRL claim is known to be actually false. The
PRA claim is not known to be false, though it is known that the proof given in PRA is
Or, if the authors refused to correct their false PRL claim,
would PRL consider another Comment? The PRL editor flatly refused to raise the issue of an
Erratum with the authors, and stated that once a Comment on a paper had been rejected, no further
Comment submissions on that paper would be considered.
My conclusion from all this is the same as the conclusion for Journal of Physics A stated above:
PRL has no discernible interest in correcting erroneous work which it has published.
The lengthy details of my extensive interaction with PRL can be found in the August 18, 2012 entry.
Standards of Physical Review A (PRA):
I have long realized that all the Physical Review journals with which I am familiar, including PRL,
PRA, and Phys. Rev. D, publish many papers which are of poor quality and not infrequently outright wrong.
To detail the reasons for this impression would require many pages which would doubtless
strain the reader's patience.
PRA's editorial judgement was poor. It was not necessarily the editor's fault that incompetent referees
were selected, but it should have been obvious from their reports that they were either incompetent or
lacking in integrity (e.g., they both failed to address the incorrect matrix multiplication which was
the essence of the Comment).
Also, PRA's published standards for evaluating Comment submissions were not followed. The published
standards state that the Comment is first sent to the authors of the commented paper, who return a response
(not a formal Reply for publication) which is sent to the author of the Comment. The very sensible idea is to see
how much agreement might be reached in informal exchanges.
However, this was (deliberately) not done in this case. The editor did send the Comment to the authors,
who returned a response that they had decided to ignore the Comment, even if it should be correct. This
response was not sent to me until I specifically asked about it.
PRA seemed to treat the authors' refusal to discuss their paper or the Comment submission
as completely normal and proper. In so doing they were actively enabling the authors' "stonewall" tactics.
It is incomprehensible to me why PRA apparently made no attempt to induce the authors to cooperate
in the evaluation of the Comment prior to the report of the adjudicator of the appeal of the initial rejection.
When the issue is whether two 2 x 2 matrices have been multiplied correctly,
why should it have been necessary to consult two referees and allow a three-month appeal to drag on?
That said, of the three journals PRL, JPA, and PRA, without doubt PRA comes out the best.
Despite the many questionable aspects of PRA's editorial procedures, it does have a defined appeal
process which did work in this case. The most important erroneous claim of the PRA version of
DJ was corrected in print.
The details of my interaction with PRA can be found in the October 27, 2013 entry.
(The full details are accessed via a link at the bottom of the entry.}
A brief summary is given above in item (d) of (2) above (titled New information on the standards
of Journal of Physics A (JPA)).
Final assessment of the standards of Journal of Physics A (JPA):
As regards DJcorr, this is covered above under the "new information" heading,
so I'll just make a few additional remarks here.
The impression that I have gained from my interactions with this journal is that it
entirely lacks integrity. Besides the deficiencies noted above, JPA often ignores
A typical example is a November 4, 2012 letter raising various issues
which should concern any journal with integrity (e.g., whether the Lemma
of DJcorr would actually prove the claimed "General theorem" of DJ) as DJcorr
asserts. This letter was initially ignored. After a second inquiry,
JPA did reply to my request for the referees' reports for
my rejected Comment that they had held for almost a year.
(They admitted that there were no referees' reports apart from
a few superficial comments from a member of the Editorial Board.)
The reply which admitted that there were no external referees' reports
promised to reply later to the rest of the Nov. 4 letter, but JPA never did.
The letter also responds to an astonishing suggestion from JPA. I had actually
simultaneously submitted two Comment papers to DJ. The longer and more important
one discussed above pointed out a gap in DJ's main result which it calls the "General theorem".
The other Comment pointed out a simple way to accomplish something which DJ treated
in a more complicated and less satisfactory manner.
The shorter Comment was rejected on the grounds that it was too trivial.
[I do not dispute its mathematical triviality, but it is an important triviality whichHowever, the author of the rejection (an unnamed member of JPA's Editorial Board)
Dressel and Jordan somehow overlooked in DJ. There were no external
referees' reports for this Comment, either. ]
made the astonishing suggestion that despite its triviality, JPA would consider the Comment
if it were submitted as a paper coauthored with Dressel and Jordan! Anyone who suspects
that I may be distorting what JPA offered can find it here verbatim.
Dressel and Jordan had nothing to do with the Comment; in fact they had refused to
communicate with me for months. Almost all journals consider it unethical to add authors
to a paper who have contributed nothing to it. That a paper which I alone had written was
considered too trivial for JPA, but would nevertheless be considered if I agreed to add
other authors who had nothing to do with it well illustrates why I consider that
JPA lacks integrity.
More details on my interactions with JPA can be found in the November 23, 2012 entry.
