One-loop corrections to the Nielsen-Olesen vortex: finite length
Jürgen Baacke
We consider the one-loop quantum corrections to the Nielsen-Olesen flux tube of finite length , by imposing periodic boundary conditions. The calculations are based on a recent…
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…
One-loop corrections to the Nielsen-Olesen vortex: collective oscillations
Jurgen Baacke
We connect the translation modes of the instanton in the two-dimensional Abelian Higgs model with local translations of the vortex of the related model in (3+1) dimensions, the Nie…
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,…
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…
