Viscous Brane Cosmology with a Brane-Bulk Energy Interchange Term
Iver Brevik, Jon-Mattis Borven, Sebastian Ng
We assume a flat brane located at y=0, surrounded by an AdS space, and consider the 5D Einstein equations when the energy flux component of the energy-momentum tensor is related to…
Viscous FRW Cosmology in Modified Gravity
I. Brevik, O. Gorbunova, Y. A. Shaido
We discuss a modified form of gravity implying that the action contains a power αof the scalar curvature. Coupling with the cosmic fluid is assumed. As equation of state for the fl…
Entropy Bound for the TM Electromagnetic Field in the Half Einstein Universe
I. Brevik, R. Herikstad, S. Skriudalen
An explicit calculation is given of the entropy/energy ratio for the TM modes of the electromagnetic field in the half Einstein universe. This geometry provides a mathematically co…
Calculation of the Casimir Force between Similar and Dissimilar Metal Plates at Finite Temperature
V. S. Bentsen, R. Herikstad, S. Skriudalen +2
The Casimir pressure is calculated between parallel metal plates, containing the materials Au, Cu, or Al. Our motivation for making this calculation is the need of comparing theore…
Meson mass and confinement force driven by dilaton
Iver Brevik, Kazuo Ghoroku, Akihiro Nakamura
Meson spectra given as fluctuations of a D7 brane are studied under the background driven by the dilaton. This leads to a dual gauge theory with quark confinement due to the gauge…
Dark Energy and Viscous Cosmology
I. Brevik, O. Gorbunova
Singularities in the dark energy universe are discussed, assuming that there is a bulk viscosity in the cosmic fluid. In particular, it is shown how the physically natural assumpti…
