Evolution of dissipative and non-dissipative universes in holographic cosmological models with a power-law term
Nobuyoshi Komatsu
Density perturbations related to structure formations are expected to be different in dissipative and non-dissipative universes, even if the background evolution of the two univers…
Entropy production due to adiabatic particle creation in a holographic dissipative cosmology
Nobuyoshi Komatsu
Cosmological adiabatic particle creation results in the generation of irreversible entropy. The evolution of this entropy is examined in a flat Friedmann--Robertson--Walker univers…
Horizon thermodynamics in holographic cosmological models with a power-law term
Nobuyoshi Komatsu
Thermodynamics on the horizon of a flat universe at late times is studied in holographic cosmological models that assume an associated entropy on the horizon. In such models, a $Λ(…
Generalized thermodynamic constraints on holographic-principle-based cosmological scenarios
Nobuyoshi Komatsu
The holographic principle can lead to cosmological scenarios, i.e., holographic equipartition models. In this model, an extra driving term (corresponding to a time-varying cosmolog…
Thermodynamic constraints on a varying cosmological-constant-like term from the holographic equipartition law with a power-law corrected entropy
Nobuyoshi Komatsu
A power-law corrected entropy based on a quantum entanglement is considered to be a viable black-hole entropy. In this study, as an alternative to Bekenstein-Hawking entropy, a pow…
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…
