Renormalization Group Improved Optimized Perturbation Theory: Revisiting the Mass Gap of the O(2N) Gross-Neveu Model

J. -L. Kneur, A. Neveu

We introduce an extension of a variationally optimized perturbation method, by combining it with renormalization group properties in a straightforward (perturbative) form. This lea…

Thermodynamics and Phase Structure of the Two-Flavor Nambu--Jona-Lasinio Model Beyond Large-N_c

Jean-Loic Kneur, Marcus Benghi Pinto, Rudnei O. Ramos

The optimized perturbation theory (OPT) method is applied to the version of the Nambu--Jona-Lasinio (NJL) model both at zero and at finite temperature and/or density. At th…
