Kontsevich product and gauge invariance
Ashok Das, Josif Frenkel
We analyze the question of gauge invariance in a flat non-commutative space where the parameter of non-commutativity, , is a local function satisfying J…
Anomalous Magnetic Moment of Electron in Chern-Simons QED
Ashok Das, Silvana Perez
We calculate the anomalous magnetic moment of the electron in the Chern-Simons theory in 2+1 dimensions with and without a Maxwell term, both at zero temperature as well as at fini…
Finite Temperature Field Theories on the Light-Front
Ashok Das
In this talk, we describe our present understanding of thermal field theories on the light-front with an application to Schwinger model.
Background field quantization and non-commutative Maxwell theory
Ashok Das, J. Frenkel, S. H. Pereira +1
We quantize non-commutative Maxwell theory canonically in the background field gauge for weak and slowly varying background fields. We determine the complete basis for expansion un…
Transport equation for the photon Wigner operator in non-commutative QED
F. T. Brandt, Ashok Das, J. Frenkel
We derive an exact quantum equation of motion for the photon Wigner operator in non-commutative QED, which is gauge covariant. In the classical approximation, this reduces to a sim…
Light-front Schwinger Model at Finite Temperature
Ashok Das, Xingxiang Zhou
We study the light-front Schwinger model at finite temperature following the recent proposal in \cite{alves}. We show that the calculations are carried out efficiently by working w…
