We study the phase diagram in a two and three dimensional periodic box at a fixed thermal to spatial aspect ratio, $\\frac{\\beta}{\\ell}$, with a flavor independent chemical potential. We assume the bilinear condensate, when one exists, has a specific momentum in the spatial direction(s). The main known features of the phase diagram in the $\\ell\\to\\infty$ limit of the two dimensional model are also seen on a finite $\\ell\\times\\beta$ torus -- a phase with a homogeneous (zero momentum) condensate; a phase with an inhomogeneous (non-zero momentum) condensate and a phase with no condensate. We observe that the inhomogeneous phase contains several sub-phases characterized by a specific spatial momentum. Unlike the two dimensional model, we do not find evidence for a phase with a inhomogeneous condensate in the three dimensional model.", "revisions": [ { "version": "v1", "updated": "2020-01-24T21:26:41.000Z" } ], "analyses": { "keywords": [ "phase diagram", "finite periodic box", "gross-neveu model", "dimensional model", "condensate" ], "note": { "typesetting": "TeX", "pages": 26, "language": "en", "license": "arXiv", "status": "editable" } } }
