Erratum: One-loop corrections to the string tension of the vortex in the Abelian Higgs model
Jurgen Baacke, Nina Kevlishvili
We correct two errors in our previous computation of one-loop corrections to the vortex string tension: (i) the contribution of the longitudinal and timelike modes of the gauge fie…
Coupled scalar fields in a flat FRW universe: renormalisation
Jurgen Baacke, Laura Covi, Nina Kevlishvili
We study the non-equilibrium dynamics of a system of coupled scalar fields in a Friedmann-Robertson-Walker (FRW) universe. We consider the evolution of spatially homogeneous "class…
Initial time singularities and admissible initial states for a system of coupled scalar fields
Jurgen Baacke, Nina Kevlishvili
We discuss the problem of initial states for a system of coupled scalar fields out of equilibrium in the one-loop approximation. The fields consist of classical background fields,…
Inhomogeneous baryogenesis, cosmic antimatter, and dark matter
A. D. Dolgov, M. Kawasaki, N. Kevlishvili
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 ast…
One-loop corrections to the string tension of the vortex in the Abelian Higgs model
Jurgen Baacke, Nina Kevlishvili
We present an exact numerical computation of the one-loop correction of the string tension for the Nielsen-Olesen vortex in the Abelian Higgs model. The computations proceeds via t…
Quantum back-reaction of the superpartners in a large-N supersymmetric hybrid model
J. Baacke, N. Kevlishvili, J. Pruschke
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. Bu…
