Propagators with the Mandelstam-Leibbrandt Prescription in the Light-Cone Gauge
Ashok Das, J. Frenkel
We show that the Feynman propagator in the light-cone gauge with the Mandelstam-Leibbrandt prescription has a logarithmic growth for large which is related to th…
The Algebra of Transition Matrices for the AdS_5 x S^5 Superstring
Ashok Das, Jnanadeva Maharana, A. Melikyan +1
We consider integrability properties of the superstring on background and construct a new one parameter family of currents which satisfies the vanishing curva…
Path Integral Approach to Residual Gauge Fixing
Ashok Das, J. Frenkel, Silvana Perez
In this paper we study the question of residual gauge fixing in the path integral approach for a general class of axial-type gauges including the light-cone gauge. We show that the…
Matter-antimatter asymmetry without departure from thermal equilibrium
José Manuel Carmona, José Luis Cortés, Ashok Das +2
We explore the possibility of baryogenesis without departure from thermal equilibrium. A possible scenario is found, though it contains strong constraints on the size of the …
Quantization in a General Light-front Frame
Ashok Das, Silvana Perez
In this paper, we study the question of quantization of quantum field theories in a general light-front frame. We quantize scalar, fermion as well as gauge field theories in a syst…
Monodromy Matrix in the PP-Wave Limit
Ashok Das, Jnanadeva Maharana, A. Melikyan
We construct the monodromy matrix for a class of gauged WZWN models in the plane wave limit and discuss various properties of such systems.
