Report

On the Supersymmetric Spectra of two Planar Integrable Quantum Systems

Autor: Leon, M. A. Gonzalez, Mayado, M. de la Torre, Guilarte, J. Mateos, Senosiain, M. J.

Two planar supersymmetric quantum mechanical systems built around the quantum integrable Kepler/Coulomb and Euler/Coulomb problems are analyzed in depth. The supersymmetric spectra of both systems are unveiled, profiting from symmetry operators not r

Report

Quantum fluctuations around low-dimensional topological defects

Autor: Guilarte, J. Mateos, Alonso-Izquierdo, A., Fuertes, W. Garcia, Mayado, M. de la Torre, Senosiain, M. J.

Publikováno v: PoS ISFTG2009:013,2009

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 spectral heat kernel/zeta function regularization procedure, and it is first

Report

Quantum scalar fields in the half-line. A heat kernel/zeta function approach

Autor: Guilarte, J. Mateos, Munoz-Castaneda, J. M., Senosiain, M. J.

Publikováno v: Mathematical Physics and Field Theory, Julio Abad, in memoriam. PUZ June 2009, 277-287

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 partition function and the spectral zeta function are calculated in terms

On the semiclassical mass of ${\mathbb S}^2$-kinks

Autor: Izquierdo, A. Alonso, Leon, M. A. Gonzalez, Guilarte, J. Mateos, Senosiain, M. J.

One-loop mass shifts to the classical masses of stable kinks arising in a massive non-linear ${\mathbb S}^2$-sigma model are computed. Ultraviolet divergences are controlled using the heat kernel/zeta function regularization method. A comparison betw

On linear operators and bases on Köthe spaces

Autor: Maldonado M., Prada J., Senosiain M. J.

Publikováno v: Applied Mathematics and Nonlinear Sciences, Vol 1, Iss 2, Pp 617-624 (2016)

We make a survey of results published by the authors about the backward and forward unilateral weighted shift operators in Kóthe spaces, the so-called generalized derivation and integration operators, extending well-known results for spaces of analy
