Power-law entropy corrected new holographic scalar field models of dark energy
Power-law holographic scalar field models dark energy PLECHDE model
2011/8/11
Abstract: In this work, the PLECHDE model with Granda-Oliveros infrared cutoff is studied and the evolution of dark energy density, deceleration and EoS parameters are calculated. I demonstrate that u...

Considering the power-law corrections to the black hole entropy, which appear in dealing with the entanglement of quantum fields in and out the horizon, the holographic energy density is modified acco...
In chameleon field theories a scalar field can couple to matter with gravitational strength and still evade local gravity constraints due to a combination of self-interactions and the couplings to mat...
