ITMP Seminar "Chiral phase transition in Gross-Neveu model"

ITMP Seminar
20 ноября 2023

Dear Colleagues,

We are pleased to announce that the next ITMP seminar will be held on Wednesday, Nov 22, 18:00 (Moscow time). It will be organised via Zoom.

Speaker: Prof. Konstantin Zarembo, Nordita & Niels Bohr Institute

Title: Chiral phase transition in Gross-Neveu model

Abstract: In the Gross-Neveu model, just like in QCD, chiral symmetry is spontaneously broken in vacuum but can be restored at finite temperature and density. Mean-field theory (large-N) predicts a phase diagram remarkably similar to that of QCD with an emergent crystalline phase arising due to Peierls instability. Translations however cannot be broken in 1d due to Landau theorem. That calls for an exact solution not relying on the mean-field approximation. Since GN model is integrable one can exploit Bethe Ansatz to study its thermodynamics. I will discuss what the Bethe Ansatz predicts for the phase structure and excitation spectrum.

If you want to join the seminar please register here before 16:00, November 22 here.
