Emergence of Tricritical Point and Liquid-Gas Phase in the Massless 2+1 Dimensional Gross-Neveu Model
Jean-Loic Kneur, Marcus Benghi Pinto, Rudnei O. Ramos +1
A complete thermodynamical analysis of the 2+1 dimensional massless Gross-Neveu model is performed using the optimized perturbation theory. This is a non-perturbative method that a…
Updating the Phase Diagram of the Gross-Neveu Model in 2+1 Dimensions
Jean-Loic Kneur, Marcus Benghi Pinto, Rudnei O. Ramos +1
The method of optimized perturbation theory (OPT) is used to study the phase diagram of the massless Gross-Neveu model in 2+1 dimensions. In the temperature and chemical potential…
The 2d Gross-Neveu Model at Finite Temperature and Density with Finite Corrections
Jean-Loic Kneur, Marcus Benghi Pinto, Rudnei O. Ramos
We use the linear expansion, or optimized perturbation theory, to evaluate the effective potential for the two dimensional Gross-Neveu model at finite temperature and density o…
