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-$…
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…
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…
