Holographic entanglement entropy: near horizon geometry and disconnected regions
Holographic entanglement entropy horizon geometry disconnected regions

We study the finite term of the holographic entanglement entropy for the charged black hole in AdS(d+2) and other examples of black holes when the spatial region in the boundary theory is given by one...
Chaotic Maps, Hamiltonian Flows, and Holographic Methods

Holographic functional methods are introduced as probes of discrete time-stepped maps that lead to chaotic behavior. The methods provide continuous time interpolation between the time steps, thereby r...
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...

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 ...
The physical origin of holographic dark energy (HDE) is reexamined. It is shown that the well-accepted explanation in terms of the UV/IR connection argument of Cohen et al is wrong. Moreover, Thomas's...
Using the Wald's relation between the Noether charge of diffeomorphisms and the entropy for a generic spacetime possessing a bifurcation surface, we introduce a method to obtain a family of higher ord...

Holographic superconductors Born-Infeld electrodynamics
2010/3/18
We study the effects of the Born-Infeld electrodynamics on the holographic superconductors in the background of a Schwarzschild AdS black hole spacetime. We find that the presence of Born-Infeld scale...
We present a holographic description of four-dimensional single-scalar inflationary universes in terms of a three-dimensional quantum field theory. The holographic description correctly reproduces sta...

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...
Holographic Quantum Foam

2010/3/17
Due to quantum fluctuations, probed at small scales, spacetime is very complicated -- something akin in complexity to a turbulent froth which the late John Wheeler dubbed quantum foam, aka spacetime f...

Fluctuating Twistor-Beam Solutions Holographic Pre-Quantum Kerr-Schild Geometry
2010/3/17
Kerr-Schild (KS) geometry is based on a congruence of twistor null lines which forms a holographic space-time determined by the Kerr theorem. We describe in details integration of the non-stationary D...

Holographic data from the prototype airborne digital holographic instrument HOLODEC (Holographic Detector for Clouds), taken during test flights are digitally reconstructed to obtain the size (equival...
