Weak magnetic field effects on chiral critical temperature in a nonlocal Nambu--Jona-Lasinio model
arXiv:1410.7266 · doi:10.1142/S0217751X15501237
Abstract
In this article we study the nonlocal Nambu--Jona-Lasinio model with a Gaussian regulator in the chiral limit. Finite temperature effects and the presence of a homogeneous magnetic field are considered. The magnetic evolution of the critical temperature for chiral symmetry restoration is then obtained. Here we restrict ourselves to the case of low magnetic field values, being this a complementary discussion to the exisiting analysis in nonlocal models in the strong magnetic field regime.
