Starting from the universal entropy bounds suggested by Bekenstein and Susskind and applying them to the black-body radiation situation, we get a cut-off of space x ≥ lP with ≥ 0.1. We go further ...
Hawking Radiation and Entropy from Horizon Degrees of Freedom
Hawking Radiation Entropy Horizon Degrees
2010/12/24
We study the thermodynamic properties of horizons using the dynamical description of the gravitational degrees of freedom at a horizon derived in an earlier work. We use the action of the horizon degr...
Entropy Production during Asymptotically Safe Inflation
Entropy Production Asymptotically Safe Inflation
2010/12/23
The Asymptotic Safety scenario predicts that the deep ultraviolet of Quantum Einstein Gravity is governed by a nontrivial renormalization group fixed point. Analyzing its implications for cosmology us...
Entanglement entropy of two disjoint intervals in conformal field theory II
Entanglement entropy disjoint intervals conformal field theory II
2010/12/24
We continue the study of the entanglement entropy of two disjoint intervals in conformal field theories that we started in J. Stat. Mech. (2009) P11001. We compute Tr\rho_A^n for any integer n for the...
Scalar field reconstruction of power-law entropy-corrected holographic dark energy
Scalar field reconstruction power-law entropy-corrected holographic dark energy
2010/12/24
A so called "power-law entropy-corrected holographic dark energy" (PLECHDE) was recently proposed to explain the dark energy dominated universe. This model is based on the power-law corrections to bl...
Entropy of extremal black holes from entropy of quasiblack holes
Entropy of extremal black holes entropy quasiblack holes
2010/12/27
The entropy of extremal black holes (BHs) is obtained using a continuity argument from extremal quasiblack holes (QBHs). It is shown that there exists a smooth limiting transition in which (i) the sys...
Permutation operators, entanglement entropy, and the XXZ spin chain in the limit Δ-> -1
Permutation operators entanglement entropy the XXZ spin chain
2010/12/24
In this paper we develop a new approach to the investigation of the bi-partite entanglement entropy in integrable quantum spin chains. Our method employs the well-known replica trick, thus taking a re...
Entanglement Entropy of Two Black Holes and Entanglement Entropic Force
Entanglement Entropy Two Black Holes Entanglement Entropic Force
2010/12/21
We study the entanglement entropy, SC, of a massless free scalar field on the outside region C of two black holes A and B whose radii are R1 and R2 and how it depends on the distance, r(≫ R1,R2)...
Back reaction, emission spectrum and entropy spectroscopy
Back reaction emission spectrum entropy spectroscopy
2010/12/22
Recently, an interesting work, which reformulates the tunneling framework to directly produce the Hawking emission spectrum and entropy spectroscopy in the tunneling picture, has been received a broad...
Holographic entanglement entropy: near horizon geometry and disconnected regions
Holographic entanglement entropy horizon geometry disconnected regions
2010/12/22
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...
Entropy Conservation of Linear Dilaton Black Holes in Quantum Corrected Hawking Radiation
Entropy Conservation Linear Dilaton Black Holes Quantum Corrected
2010/3/18
It has been shown recently that information is lost in the Hawking radiation of the linear dilaton black holes in various theories when applying the tunneling formulism without considering quantum gra...
The entropy and mean separation between energy levels of black hole
mean separation energy levels black hole
2010/3/17
According to the widely accepted statistical interpretation of black hole entropy the mean separation between energy levels of black hole should be exponentially small. But this sharply disagrees with...
Dynamical Horizon Entropy Bound Conjecture in Loop Quantum Cosmology
entropy bound conjecture Loop Quantum Cosmology
2010/3/17
The covariant entropy bound conjecture is an important hint for the quantum gravity, with several versions available in the literature. For cosmology, Ashtekar and Wilson-Ewing ever show the consisten...
