Thermodynamic aspects of entropic cosmology with viscosity
I. Brevik, A. V. Timoshkin
We describe the evolution of the early and late universe from thermodynamic considerations, using the generalized non-extensive Tsallis entropy with a variable exponent. A new elem…
Remarks on the Abraham-Minkowski problem, from the formal and from the experimental side
Iver Brevik, Masud Chaichian, Ion I. Cotăescu
We analyze the Abraham-Minkowski problem known from classical electrodynamics from two different perspectives. First, we follow a formal approach, implying use of manifolds with cu…
Classical and quantal aspects of Minkowski's four-momentum in analog gravity
Iver Brevik
The electrodynamic theory of continuous media is probably the most convenient platform when trying to construct analog gravity theories. Quite naturally, this topic has gained cons…
Non-trivial retardation effects in dispersion forces: From anomalous distance dependence to novel traps
Johannes Fiedler, Kristian Berland, Fabian Spallek +4
In the study of dispersion forces, nonretarded, retarded and thermal asymptotes with their distinct scaling laws are regarded as cornerstone results governing interactions at diffe…
Remarks on cosmological bulk viscosity in different epochs
Iver Brevik, Ben David Normann
The intention of this paper is mainly two-fold. \textit{First}, we point out a striking numerical agreement between the bulk viscosity in the lepton era calculated by Husdal (2016)…
Rip brane cosmology from a viscous holographic dark fluid
I. Brevik, A. V. Timoshkin
This article is devoted to the application of the holographic principle to describe Rip brane cosmological models in the presence of a bulk viscosity. We make use of the generalize…
