Renormalization Group approach to universality in non-integrable systems (Vieri Mastropietro, University of Milan)

02.12.2019 16:00 – 17:00

I will present a review of results obtained by rigorous Renormalization Group methods on the universality problem in 2D statistical mechanics systems, including Ising, Dimer or vertex models and their non integrable generalizations. The exponents and amplitudes are written as series, convergent for values of parameters near the free fermion point and dependent on all the parameters. The validity of universal scaling relations follows by subtle cancellations due to emergent symmetries in the series expansions
