Fermion propagator in an external potential and generalized Airy functions
A. L. M. Britto, Ashok K. Das, J. Frenkel
We study the behavior of the fermion propagator in an external time dependent potential in 0+1 dimension. We show that, when the potential has upto quadratic terms in time, the pro…

Generalized Kadanoff-Baym relation in nonequilibrium quenched models
A. L. M. Britto, Ashok K. Das, J. Frenkel
In the context of a broad class of quenched models, we derive a generalized differential form of the Kadanoff-Baym (KB) ansatz which relates the out of equilibrium correlated and s…
