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…
Effective potential for a covariantly constant gauge field in curved spacetime
Emilio Elizalde, Sergei D. Odintsov, August Romeo
We discuss the influence of gravitational effects on the stabilization of the chromomagnetic vacuum. The one-loop effective potential for a covariantly constant SU(2) gauge field i…
The Gross-Neveu model on a sphere with a magnetic monopole
E. Elizalde, S. Naftulin, S. D. Odintsov
We study, for the first time, the phase structure of the Gross--Neveu model with a combination of a (constant) gravitational and a magnetic field. This has been made possible by ou…
Simplified treatment of the radiative transfer problem in expanding envelopes
J. Gomez-Gomar, J. Isern
In this paper we study the application of a simplified method to solve the dynamic radiative transfer problem in expanding envelopes. The method, which requires a computational eff…
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…
On the ^7 Li and ^7 Be synthesis in novae
M. Hernanz, J. Jose, A. Coc +1
The production of ^7 Li and ^7 Be during the explosive hydrogen-burning that occurs in nova explosions is computed by means of a hydrodynamic code able to treat both the accretion…
