Chiral Ward-Takahashi Identities at Finite Temperature and Chiral Phase Transition in (2+1) Dimensional Chiral Gross-Neveu Model

  • Chiral Ward-Takahashi identities at finite remperature are derived in (2+1) dimensional chiral Gross-Neveu model.In terms of these identities,fermion mass generation and the mass spectra of bound states are investigated at finite temperature.Taking the fermion mass as an order parameter,we discuss the phase structure and chiral phase transition and obtain the critical temperature.

Abstract: Chiral Ward-Takahashi identities at finite remperature are derived in (2+1) dimensional chiral Gross-Neveu model.In terms of these identities,fermion mass generation and the mass spectra of bound states are investigated at finite temperature.Taking the fermion mass as an order parameter,we discuss the phase structure and chiral phase transition and obtain the critical temperature.
