Perturbative, Nonperturbative and Exact Aspects of Crystalline Phases in the Gross-Neveu Model

Francesco Benini, Ohad Mamroud, Tomas Reis +1

We study the crystalline phase of the $O(2N)$ Gross--Neveu model with a chemical potential for $a\le N-2$ of the fermions. We analyze the problem in three independent ways: using…
