Renormalization Group Approach to 2D Probabilistic Models
Abstract:
Many two-dimensional lattice models of Statistical
Mechanics can be re-casted as a system of 'interacting fermions':
Ising, 6-vertex, 8-vertex, Ashkin-Teller, q-States Potts, Hubbard
(d=1+1) , XYZ quantum chain (d=1+1), etc.
In the seminar I will discuss some works in collaboration with
G.Benfatto and V. Mastropietro in which we use (rigorous)
renormalization group approach to study, in some of the above models,
the critical exponents of the second order phase transition.
