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…
Some General Results for Multi-dimensional Compactonsin Generalized N-dimensional KdV Equations
Fred Cooper, Avinash Khare, Avadh Saxena
We derive a general theorem relating the energy and momentum with the velocity of any solitary wave solution of the generalized KdV equation in -dimensions that follows from an…
On the forward cone quantization of the Dirac field in "longitudinal boost-invariant" coordinates with cylindrical symmetry
Bogdan Mihaila, John F. Dawson, Fred Cooper
We obtain a complete set of free-field solutions of the Dirac equation in a (longitudinal) boost-invariant geometry with azimuthal symmetry and use these solutions to perform the c…
Phases of a fermionic model with chiral condensates and Cooper pairs in 1+1 dimensions
Bogdan Mihaila, Krastan B. Blagoev, Fred Cooper
We study the phase structure of a 4-fermi model with three bare coupling constants, which potentially has three types of bound states. This model is a generalization of the model d…
