An alternative calculation of the Casimir energy for kappa-deformed electrodynamics
D Pinheiro, F C Santos, A. C. Tort
A simple, but effcient way of calculating regularized Casimir energies suitable for non-trivial frequency spectra is briefly described and applied to the case of a kappa-deformed s…
Duality Transformations and temperature inversion symmetry
F C Santos, A C Tort
We argue that the temperature inversion symmetry present in the original Casimir setup and also in other Casimir systems for which symmetrical boundary conditions are imposed is no…
The non-retarded dispersive force between an electrically polarizable atom and a magnetically polarizable one
C. Farina, F. C. Santos, A. C. Tort
Using perturbative QED we show that, while the retarded dispersive force between an electrically polarizable atom and a magnetically polarizable one is proportional to , w…
Zeta Function Method for Repulsive Casimir Forces at Finite Temperature
F. C. Santos, A. Tenório, A. C. Tort
We compute the Casimir energy between an unusual pair of parallel plates at finite temperature, namely, a perfectely conducting plate () and an infinitely permeable one…
