Quantum fluctuations of topological -kinks
A. Alonso Izquierdo, M. A. Gonzalez Leon, J. Mateos Guilarte +1
The kink Casimir effect in the massive non-linear -sigma model is analyzed.
Quantum fluctuations around low-dimensional topological defects
J. Mateos Guilarte, A. Alonso-Izquierdo, W. Garcia Fuertes +2
In these Lectures a method is described to analyze the effect of quantum fluctuations on topological defect backgrounds up to the one-loop level. The method is based on the spectra…
Quantum scalar fields in the half-line. A heat kernel/zeta function approach
J. Mateos Guilarte, J. M. Munoz-Castaneda, M. J. Senosiain
In this paper we shall study vacuum fluctuations of a single scalar field with Dirichlet boundary conditions in a finite but very long line. The spectral heat kernel, the heat part…
On the semiclassical mass of -kinks
A. Alonso Izquierdo, M. A. Gonzalez Leon, J. Mateos Guilarte +1
One-loop mass shifts to the classical masses of stable kinks arising in a massive non-linear -sigma model are computed. Ultraviolet divergences are controlled using…
