Schwinger Mechanism for Fermion Pair Production in the Presence of Arbitrary Time Dependent Background Electric Field
Fred Cooper, Gouranga C. Nayak
We study the Schwinger mechanism for the pair production of fermions in the presence of an arbitrary time-dependent background electric field E(t) by directly evaluating the path i…

Schwinger Mechanism in the Presence of Arbitrary Time Dependent Background Electric Field
Fred Cooper, Gouranga C. Nayak
We study, for the first time, the Schwinger mechanism for the pair production of charged scalars in the presence of an arbitrary time-dependent background electric field E(t) by by…

Shift Theorem Involving the Exponential of a Sum of Non-Commuting Operators in Path Integrals
Fred Cooper, Gouranga C. Nayak
We consider expressions of the form of an exponential of the sum of two non-commuting operators of a single variable inside a path integration. We show that it is possible to shift…
