Vacuum energy of scalar fields on spherical shells with general matching conditions
Guglielmo Fucci, César Romaniega Sancho
In this work we analyze the spectral zeta function for massless scalar fields propagating in a -dimensional flat space under the influence of a shell potential. The shell potent…
Casimir self-energy of a δ-δ' sphere
C. Romaniega, J. M. Munoz-Castaneda, I. Cavero-Pelaez
We extend previous work on the vacuum energy of a massless scalar field in the presence of singular potentials. We consider a single sphere denoted by the so-called "delta-delta pr…
Casimir energy for spinor fields with -shell potentials
Guglielmo Fucci, César Romaniega Sancho
This work analyzes the Casimir energy of a massive spinor field propagating in flat space endowed with a spherically symmetric -function potential. By utilizing the spectral zet…
Casimir-Lifshitz pressure on cavity walls
C. Romaniega
We extend our previous work on the electromagnetic Casimir-Lifshitz interaction between two bodies when one is contained within the other. We focus on the fluctuation-induced press…
Casimir Energy for concentric - spheres
Ines Cavero-Pelaez, Jose M. Munoz-Castaneda, Cesar Romaniega
We study the vacuum interaction of a scalar field and two concentric spheres defined by a singular potential on their surfaces. The potential is a linear combination of the Dirac-$…
Repulsive Casimir-Lifshitz pressure in closed cavities
C. Romaniega
We consider the interaction pressure acting on the surface of a dielectric sphere enclosed within a magnetodielectric cavity. We determine the sign of this quantity regardless of t…
Some recent results on contact or point supported potentials
Luis M. Nieto, Manuel Gadella, Juan M. Mateos-Guilarte +2
We introduced some contact potentials that can be written as a linear combination of the Dirac delta and its first derivative, the - interaction. After a simple general pres…
An approximation to the Woods-Saxon potential based on a contact interaction
C. Romaniega, M. Gadella, R. M. Id Betan +1
We study a non-relativistic particle subject to a three-dimensional spherical potential consisting of a finite well and a radial - contact interaction at the well edge. This…
Hyperspherical potentials
J. M. Munoz-Castaneda, L. M. Nieto, C. Romaniega
The spherically symmetric potential is generalised for the -dimensional space as a characterisation of a unique selfadjoint extension of the free Ha…
