Transition Radiation and the Origin of Sonoluminescence
B. Jensen, I. Brevik
It has been shown by Liberati et al. [quant-ph/9904013] that a dielectric medium with a time-dependent refractive index may produce photons. We point out that a free electric charg…
Magnetohydrodynamics in the Inflationary Universe
I. Brevik, H. B. Sandvik
Magnetohydrodynamic (MHD) waves are analysed in the early Universe, in the inflationary era, assuming the Universe to be filled with a nonviscous fluid of the Zel'dovich type ($p=ρ…
Energy Production in the Formation of a Finite Thickness Cosmic String
I. Brevik, A. G. Frøseth
The classical electromagnetic modes outside a long, straight, superconducting cosmic string are calculated, assuming the string to be surrounded by a superconducting cylindric surf…
Self-Screening Hawking Atmosphere in the Presence of a Bulk Viscosity
I. Brevik
The recent theory of 't Hooft [ Nucl. Phys. Suppl. {\bf 68}, 174 (1998)] models the black hole as a system endowed with an envelope of matter that obeys an equation of state in the…
The Casimir Problem of Spherical Dielectrics: A Solution in Terms of Quantum Statistical Mechanics
J. S. Høye, I. Brevik
The Casimir energy for a compact dielectric sphere is considered in a novel way, using the quantum statistical method introduced by H\oye - Stell and others. Dilute media are assum…
Quantum Cosmology from \cal{N} = 4 Super Yang - Mills Theory
I. Brevik, S. D. Odintsov
We consider quantum \cal{N} = 4 super Yang-Mills theory interacting in a covariant way with \cal{N} = 4 conformal supergravity. The induced large N effective action for such a theo…
