Holographic Dark Energy Characterized by the Total Comoving Horizon and Insights to Cosmological Constant and Coincidence Problem
Holographic Dark Energy the Total Comoving Horizon Insights Cosmological Constant Coincidence Problem
2012/2/21
The observed acceleration of the present universe is shown to be well explained by the holographic dark energy characterized by the total comoving horizon of the universe ($\eta$HDE). It is of interes...
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...
By assuming that a dark component (dark energy) in the universe strictly obeys the holographic principle, that is, its entropy is one fourth of the apparent horizon, we find that the existence of the...
Observational signatures of holographic models of inflation
Observational signatures holographic models
2011/1/13
We discuss the phenomenology of recently proposed holographic models of inflation, in which the very early universe is non-geometric and is described by a dual three-dimensional quantum field theory (...
We investigate the non-Gaussianity of primordial cosmological perturbations within our recently proposed holographic description of inflationary universes. We derive a holographic formula that determi...
Towards a Holographic Description of Inflation and Generation of Fluctuations from Thermodynamics
Verlinde conjectured entropic force gravity
2010/3/19
Recently, Verlinde conjectured that gravity may be an entropic force, arising from thermodynamics on the holographic screen. We investigate the implications of the entropic force formalism for inflati...
Modified gravity emerging from thermodynamics and holographic principle
law of entropy thermodynamics holographic principle
2010/3/19
We discuss three different corrections to the area law of entropy. The number of bits $N$ is then modified according to the form of entropy, and the law of gravity is obtained by using the method deve...
Quantum UV/IR Relations and Holographic Dark Energy from Entropic Force
Quantum UV/IR Holographic Dark Energy Entropic Force
2010/3/19
We investigate the implications of the entropic force formalism proposed by Verlinde. We show that an UV/IR relation proposed by Cohen et al, as well as an uncertainty principle proposed by Hogan can ...
Holographic Superconductors in Hořava-Lifshitz Gravity
holographic superconductors Hoˇrava-Lifshitz gravity parameter of the detailed balance
2010/3/18
We study $(2+1)$-dimensional holographic superconductors in the Ho\v{r}ava-Lifshitz black hole without the condition of the detailed balance which has rich physics, i.e., changing the parameter of the...
