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

Condensates, crystals, and renormalons in the Gross-Neveu model at finite density

Francesco Benini, Ohad Mamroud, Tomas Reis +1

We study the $O (2 N)$ symmetric Gross-Neveu model at finite density in the presence of a $U (1)$ chemical potential $h$ for a generic number $a \leq N - 2$ of fermion fields. By combin…
