Thermal Operator Representation of Finite Temperature Graphs
Fernando T. Brandt, Ashok Das, Olivier Espinosa +2
Using the mixed space representation (t,p) in the context of scalar field theories, we prove in a simple manner that the Feynman graphs at finite temperature are related to the cor…

Unruh Effect in the General Light-Front Frame
Ashok Das, J. Frenkel, Silvana Perez
We study the phenomenon of Unruh effect in a massless scalar field theory quantized on the light-front in the general light-front frame. We determine the uniformly accelerating coo…
