Kruglov-entropy cosmology from apparent-horizon thermodynamics: background dynamics and observational constraints
Candrasyah Muhammad, Burin Gumjudpai, Nandan Roy +1
We investigate two late-time cosmological models generated by Kruglov's nonadditive entropy at the apparent horizon. Model I, originally derived by Kruglov, follows the Cai--Kim th…

Holographic dark energy with non-minimal derivative coupling to gravity effects
Chonticha Kritpetch, Candrasyah Muhammad, Burin Gumjudpai
Non-minimal derivative coupling (NMDC) to gravity in flat FLRW universe is investigated in the scenario of holographic dark energy. Kinetic term is coupled to the Einstein tensor u…

Palatini NMDC gravity: cosmological scalar field phase portraits in exponential potential
Candrasyah Muhammad, Somphoach Saichaemchan, Burin Gumjudpai
We consider cosmological scalar field evolving under exponential potential of the Non-minimal Derivative Coupling (NMDC) gravity model in Palatini formalism. Slow-roll regime is as…
