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.
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…
Large gauge invariance and finite temperature
Ashok Das
In this talk, I summarize the status of our understanding of the puzzle of large gauge invariance at finite temperature.
Supersymmetry in Singular Quantum Mechanics
Ashok Das
The breaking of supersymmetry due to singular potentials in supersymmetric quantum mechanics is critically analyzed. It is shown that, when properly regularized, these potentials r…
Proper Time Method for Fermions
Ashok Das, Carlos Farina
We show how Schwinger's proper time method can be used to evaluate directly the determinant of first order operators associated with fermionic theories. Several examples are worked…
