The nonlocality is incorporated in the model by using a Gaussian form factor. It is found that for low and moderate values of magnetic field there is a decrease of the critical chiral restoration chemical potential $\\mu_c$, i.e. an inverse magnetic catalysis effect is observed. For larger values of $eB$ the behavior of $\\mu_c$ becomes more or less flat, depending on the parametrization. Within the considered parametrization range we do not find a significant growth of the critical chemical potential for large magnetic fields, as occurs in the case of the local NJL model.", "revisions": [ { "version": "v1", "updated": "2021-03-01T13:17:24.000Z" } ], "analyses": { "keywords": [ "nonlocal chiral quark model", "cold magnetized quark matter", "finite density", "chiral restoration chemical potential", "magnetic field" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
