A dispersive correction to the Casimir force
Finn Ravndal, Lee-Peng Teo
Using perturbation theory the first order dispersive correction to the Casimir energy between two plates separated by a dielectric material is calculated. It falls off with the pla…
On the Casimir effect in a continuous medium
Finn Ravndal
It is pointed out that the Casimir energy in a medium can be obtained most directly from the zero-point energy of the electromagnetic field because of its reduced propagation veloc…
Effective electromagnetic theory for dielectric media
Finn Ravndal
Light in a dielectric medium moves slower than in vacuum. The corresponding electromagnetic field equations are then no longer invariant under ordinary Lorentz transformations, but…
Electromagnetic Casimir energy with extra dimensions
H. Alnes, K. Olaussen, F. Ravndal +1
We calculate the energy-momentum tensor due to electromagnetic vacuum fluctuations between two parallel hyperplanes in more than four dimensions, considering both metallic and MIT…
Black-body radiation in extra dimensions
H. Alnes, F. Ravndal, I. K. Wehus
The general form of the Stefan-Boltzmann law for the energy density of black-body radiation is generalized to a spacetime with extra dimensions using standard kinetic and thermodyn…
Scalar Field Fluctuations between Parallel Plates
Konrad Tywoniuk, Finn Ravndal
Quantum fluctuations of a scalar field and its derivatives are calculated when the field is confined between two parallel plates satisfying Dirichlet or Neumann boundary conditions…
Radiative Corrections to the Casimir Energy
Xinwei Kong, Finn Ravndal
The lowest radiative correction to the Casimir energy density between two parallel plates is calculated using effective field theory. Since the correlators of the electromagnetic f…
What is the Regularized Casimir Vacuum Energy Density?
Xinwei Kong, Finn Ravndal
The regularized total Casimir energy in spacetimes with boundaries is not in general equal to the integral of the regularized energy density. This paradoxical phenomenon is most tr…
