On the energy-momentum tensor in non-commutative gauge theories
Ashok Das, J. Frenkel
We study the properties of the energy-momentum tensor in non-commutative gauge theories by coupling them to a weak external gravitational field. In particular, we show that the str…
The static effective action for non-commutative QED at high temperature
F. T. Brandt, Ashok Das, J. Frenkel +2
In this paper, we systematically study the effective action for non-commutative QED in the static limit at high temperature. When , where represents the magnitude…
Monodromy, Duality and Integrability of Two Dimensional String Effective Action
Ashok Das, J. Maharana, A. Melikyan
In this talk, we show how the monodromy matrix, , can be constructed for the two dimensional tree level string effective action. The pole structure of ${\hat{\cal M…
Comment on "Supersymmetry in the half-oscillator - revisited"
Ashok Das, S. Pernice
We point out the flaw in the analysis of Gangopadhyaya and Mallow, hep-th/0206133, where it is claimed that supersymmetry is broken in the SUSY half-oscillator, even with a regular…
