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.
