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…
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…
One-loop corrections to the instanton transition in the Abelian Higgs model: Gel'fand-Yaglom and Green's function methods
Jurgen Baacke
The fluctuation determinant, the preexponential factor for the instanton transition, has been computed several years ago in the Abelian Higgs model, using a method based on integra…
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…
Tunneling in a quantum field theory on a compact one-dimensional space
J. Baacke, N. Kevlishvili
We compute tunneling in a quantum field theory in 1+1 dimensions for a field potential of the asymmetric double well type. The system is localized initially in the ``false v…
Self-consistent bounces in two dimensions
Jurgen Baacke, Nina Kevlishvili
We compute bounce solutions describing false vacuum decay in a Phi**4 model in two dimensions in the Hartree approximation, thus going beyond the usual one-loop corrections to the…
