The next to leading order effective potential in the 2+1 dimensional Nambu-Jona-Lasinio model at finite temperature

E. P. Esposito, I. A. Shovkovy, L. C. R. Wijewardhana

The finite temperature effective potential in the 2+1 dimensional Nambu-Jona-Lasinio model is constructed up to the next to leading order in the large $N$ expansion, where $N$ is t…
