General form of entropy on the horizon of the universe in entropic cosmology
Nobuyoshi Komatsu, Shigeo Kimura
Entropic cosmology assumes several forms of entropy on the horizon of the universe, where the entropy can be considered to behave as if it were related to the exchange (the transfe…
Cosmic microwave background radiation temperature in a dissipative universe
Nobuyoshi Komatsu, Shigeo Kimura
The relationship between the cosmic microwave background radiation temperature and the redshift, i.e., the -- relation, is examined in a phenomenological dissipative model. T…
Entropic cosmology in a dissipative universe
Nobuyoshi Komatsu, Shigeo Kimura
The bulk viscosity of cosmological fluid and the creation of cold dark matter both result in the generation of irreversible entropy (related to dissipative processes) in a homogene…
Evolution of the universe in entropic cosmologies via different formulations
Nobuyoshi Komatsu, Shigeo Kimura
We study two types of entropic-force models in a homogeneous, isotropic, spatially flat, matter-dominated universe. The first type is a ` type' similar to CDM (varying-…
Entropic cosmology for a generalized black-hole entropy
Nobuyoshi Komatsu, Shigeo Kimura
An entropic-force scenario, i.e., entropic cosmology, assumes that the horizon of the universe has an entropy and a temperature. In the present study, in order to examine entropic…
Non-adiabatic-like accelerated expansion of the late universe in entropic cosmology
Nobuyoshi Komatsu, Shigeo Kimura
In `entropic cosmology', instead of a cosmological constant , an extra driving term is added to the Friedmann equation and the acceleration equation, taking into account the ent…
