Influence of a magnetic fluxon on the vacuum energy of quantum fields confined by a bag
S. Leseduarte, August Romeo
We study the simultaneous influence of boundary conditions and external fields on quantum fluctuations by considering vacuum zero-point energies for quantum fields in the presence…
Casimir energies for massive fields in the bag
M. Bordag, K. Kirsten, E. Elizalde +1
The Casimir energy corresponding to a massive scalar field with Dirichlet boundary conditions on a spherical bag is obtained. The field is considered, separately, inside and outsid…
Complete zeta-function approach to the electromagnetic Casimir effect for spheres and circles
S. Leseduarte, August Romeo
A technique for evaluating the electromagnetic Casimir energy in situations involving spherical or circular boundaries is presented. Zeta function regularization is unambiguously u…
Phase structure of renormalizable four-fermion models in spacetimes of constant curvature
E. Elizalde, S. Leseduarte, S. D. Odintsov +1
A number of 2d and 3d four-fermion models which are renormalizable ---in the expansion--- in a maximally symmetric constant curvature space, are investigated. To this purpose…
Higher Derivative Four-Fermion Model in Curved Spacetime
E. Elizalde, S. Leseduarte, S. D. Odintsov
We discuss the phase structure of a higher derivative four-fermion model in four dimensions in curved spacetime in frames of the -expansion. First, we evaluate in ou…
Mellin Transform Techniques for Zeta-Function Resummations
E. Elizalde, S. Leseduarte, S. Zerbini
Making use of inverse Mellin transform techniques for analytical continuation, an elegant proof and an extension of the zeta function regularization theorem is obtained. No series…
Spectral Zeta Functions for Spherical Aharonov-Bohm Quantum Bags
E. Elizalde, S. Leseduarte, A. Romeo
We study the sum $\dsζ_H(s)=\sum_j E_j^{-s}$ over the eigenvalues of the Schrdinger equation in a spherical domain with Dirichlet walls, threaded by a line of magnetic flux.…
