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 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-$…
Quantum Electromagnetic Stress Tensor in an Inhomogeneous Medium
Prachi Parashar, Kimball A. Milton, Yang Li +4
Continuing a program of examining the behavior of the vacuum expectation value of the stress tensor in a background which varies only in a single direction, we here study the elect…
Searching for a -function on the three-dimensional sphere
C. G. Beneventano, I. Cavero-Peláez, D. D'Ascanio +1
We present a detailed analytic study on the three-dimensional sphere of the most popular candidates for -functions, both for Dirac and scalar free massive fields. We discuss to…
Topological Entropy and Renormalization Group flow in 3-dimensional spherical spaces
M. Asorey, C. G. Beneventano, I. Cavero-Peláez +2
We analyze the renormalization group (RG) flow of the temperature independent term of the entropy in the high temperature limit β/a<<1 of a massive field theory in 3-dimensional sp…
Multiple Scattering: Dispersion, Temperature Dependence, and Annular Pistons
Kimball A. Milton, Jef Wagner, Prachi Parashar +3
We review various applications of the multiple scattering approach to the calculation of Casimir forces between separate bodies, including dispersion, wedge geometries, annular pis…
