Effective action for QED in 2+1 dimensions at finite temperature

arXiv:hep-ph/9812386 · doi:10.1103/PhysRevD.60.067703

Abstract

We calculate the effective action for a constant magnetic field and a time-dependent time-component of the gauge field in 2+1 dimensions at finite temperature. We also discuss the behaviour of the charge density and the fermion condensate as order parameters of symmetry breaking.
