Impact of a uniform magnetic field and non-zero temperature on explicit chiral symmetry breaking in QED: arbitrary hierarchy of energy scales
A Ayala1,2,3, A Bashir1, A Raya1 and A Sánchez1
Show affiliationsEmploying Schwinger's proper-time method, we calculate the 
-condensate for massive Dirac fermions of charge e interacting with a uniform magnetic field in a heat bath. We present general results for arbitrary hierarchy of the energy scales involved, namely the fermion mass m, the magnetic field strength 
and temperature T. Moreover, we study particular regimes in detail and reproduce some of the results calculated or anticipated earlier in the literature. We also discuss possible applications of our findings.
