Particle-antiparticle asymmetry from magnetogenesis through the Landau mechanism
D. Carcamo, Ashok Das, J. Gamboa +1
Motivated by string theory an extension of the Landau problem to quantum field theory is considered. We show that the commutator between momenta of the fields violates Lorentz and…

Causal amplitudes in the Schwinger model at finite temperature
Ashok Das, R. R. Francisco, J. Frenkel
We show, in the imaginary time formalism, that the temperature dependent parts of all the retarded (advanced) amplitudes vanish in the Schwinger model. We trace this behavior to th…
