Inhomogeneous baryogenesis, cosmic antimatter, and dark matter (2008)
Dolgov, A. D., Kawasaki, M., Kevlishvili, N.
A model of inhomogeneous baryogenesis based on the Affleck and Dine mechanism is described. A simple coupling of the scalar baryon field to the inflaton allows for formation of astronomically...
Quantum back-reaction of the superpartners in a large-N supersymmetric hybrid model (2007)
Baacke, J., Kevlishvili, N., Pruschke, J.
We study the supersymmetric hybrid model near and after the end of inflation. As usual, we reduce the model to a purely scalar hybrid model on the level of the classical fields. But on the level of...
Tunneling in a quantum field theory on a compact one-dimensional space (2005)
We compute tunneling in a quantum field theory in 1+1 dimensions for a field potential $U(\Phi)$ of the asymmetric double well type. The system is localized initially in the ``false vacuum''. We...
Once Again On the Klein Paradox (2003)
Kevlishvili, N., Khelashvili, A., Nadareishvili, T.
After the short survey of the Klein Paradox in 3-dimensional relativistic equations, we present a detailed consideration of Dirac modified equation, which follows by one particle infinite...
