Rotation of the polarization plane in axion fields: application to neutron star polar cap regions
Iver H. Brevik, Moshe M. Chaichian, Tiberiu Harko +1
We study observable manifestations of an axion field, focusing on possible polarizational effects for electromagnetic wave propagating in such a special magnetoelectric medium. The…

Stefan-Boltzmann Law and Thermal Casimir Effect in Neutron Star Spacetime via Thermo Field Dynamics
K. E. L. de Farias, M. A. Anacleto, Rafael A. Batista +5
We investigate the thermal Casimir effect for a massless scalar field in the curved spacetime of a neutron star within the Thermo Field Dynamics (TFD) formalism. Starting from the…

Casimir Force and its Relation to Surface Tension
J. S. Høye, I. Brevik
From energy considerations there is reason to expect that the work done by Casimir forces during a slow displacement of the parallel plates reflects the free energy of the surface…
