Little Rip cosmological models with time-dependent equation of state

I. Brevik, V. V. Obukhov, K. E. Osetrin +1

Specific dark energy models, leading to the Little Rip (LR) cosmology in the far future, are investigated. Conditions for the occurrence of LR in terms of the parameters present in…

Particle number production and time variation with non-equilibrium quantum field theory

Ryuichi Hotta, Hiroyuki Takata, Takuya Morozumi

We study the particle number production and its time variation using non-equilibrium quantum field theory. We study the model proposed by Hotta et.al. \cite{Hotta:2012hi} for parti…

Turbulence and Little Rip Cosmology

I. Brevik, R. Myrzakulov, S. Nojiri +1

A variety of conditions is considered under which the cosmic dark fluid may be able to develop a future Big Rip or Little Rip singularity. Both one-component and two-component mode…

Coherent radiation of atoms and a channeling particle

V. Epp, M. A. Sosedova

New mechanism of radiation emitted at channeling of a relativistic particle in a crystal is studied. Superposition of coherent radiation of the atoms in a crystal lattice which are…

Dark energy cosmology: the equivalent description via different theoretical models and cosmography tests

Kazuharu Bamba, Salvatore Capozziello, Shin'ichi Nojiri +1

We review different dark energy cosmologies. In particular, we present the CDM cosmology, Little Rip and Pseudo-Rip universes, the phantom and quintessence cosmologies with Type…
