In this paper, we consider a class of cosmological fluids that possess properties analogous to those of crystalline solids undergoing isotropic deformations. Our research is based on a modified log-corrected power-law equation of state in the presence of a bulk viscosity. This formalism represents a class of the so-called logotropic fluids, and allows explaining an accelerating late-time universe. In order to obtain a more detailed picture of its evolution, we add in our model a coupling of the… Expand


Cosmological Fluids with Logarithmic Equation of State
We investigate the cosmological applications of fluids having an equation of state which is the analog to the one related to the isotropic deformation of crystalline solids, that is containingExpand
Partially relativistic self-gravitating Bose-Einstein condensates with a stiff equation of state
Because of their superfluid properties, some compact astrophysical objects such as neutron stars may contain a significant part of their matter in the form of a Bose-Einstein condensate (BEC). WeExpand
Effective field description of the Anton-Schmidt cosmic fluid
The effective theory of the Anton-Schmidt cosmic fluid within the Debye approximation is investigated. In this picture, the universe is modeled out by means of a medium without cosmological constant.Expand
Nonlinear logarithmic interactions and a varying polytropic gas
In this paper we will demonstrate possible existence of more exotic forms of interaction taking into account, that dark energy can be parametrized as a varying polytropic uid suggested recently byExpand
The new form of the equation of state for dark energy fluid and accelerating universe
We suggest to generalize the dark energy equation of state (EoS) by introduction the relaxation equation for pressure which is equivalent to consideration of the inhomogeneous EoS cosmic fluid whichExpand
Cosmological singularities in interacting dark energy models with an $\omega(q)$ parametrization
Future singularities arising in a family of models for the expanding Universe, characterized by sharing a convenient parametrization of the energy budget in terms of the deceleration parameter, areExpand
Properties of singularities in the (phantom) dark energy universe
The properties of future singularities are investigated in the universe dominated by dark energy including the phantom-type fluid. We classify the finite-time singularities into four classes andExpand
Inhomogeneous equation of state of the universe: Phantom era, future singularity and crossing the phantom barrier
The dark energy universe equation of state (EOS) with inhomogeneous, Hubble parameter dependent term is considered. The motivation to introduce such a term comes from time-dependent viscosityExpand
Viscous holographic dark energy universe with Nojiri-Odintsov cut-off
In this paper we consider a toy model of large scale universe, when one of the dark components is a generalized holographic DE with a Nojiri-Odintsov cut-off. On the other hand, we made anotherExpand
Inhomogeneous viscous dark fluid coupled with dark matter in the FRW universe
A cosmological model with an inhomogeneous viscous dark fluid coupled with dark matter in a flat Friedman-Robertson-Walker universe is investigated. The influence of dark matter on the behavior of anExpand
