Kronecker delta energy terms in thermal field theory
F. T. Brandt, Ashok Das, J. Frenkel +1
We discuss, using the imaginary time method, some aspects of the connection between the Ward identity, the non-analyticity of amplitudes and the causality relation in QED at finite…

Induced parity violating thermal effective action for (2+1)-dimensional fermions interacting with a non-Abelian background
F. T. Brandt, Ashok Das, J. Frenkel
We study the parity breaking effective action in 2+1 dimensions, generated, at finite temperature, by massive fermions interacting with a non-Abelian gauge background. We explicitl…
