Phase diagram of the massless Gross-Neveu model with two components
Michael Thies
Recently, Benini, Mamroud, Reis and Serone have presented exact results for the Gross-Neveu model at finite density, both at finite N and in the large N limit. Generalizing previou…

Peierls instability for systems with several Fermi surfaces: an example from the chiral Gross-Neveu model
Michael Thies
As is well known, the chiral Gross-Neveu model at finite density can be solved semi-classically with the help of the chiral spiral mean field. The fermion spectrum has a single gap…

Non-perturbative phase boundaries in the Gross-Neveu model from a stability analysis
Michael Thies
Two out of three phase boundaries of the 1+1 dimensional Gross-Neveu model in the chiral limit can be obtained from a standard, perturbative stability analysis of the homogeneous p…
