Static isolated horizons: SU(2) invariant phase space, quantization, and black hole entropy
Static isolated horizons invariant phase space quantization black hole entropy

We study the classical field theoretical formulation of static generic isolated horizons in a man-ifestly SU(2) invariant formulation. We show that the usual classical description requires revision in...
Rindler horizon entropy from nonstationarity

Finite entropy and energy are obtained for the horizon of a Rindler observer on the grounds of the nonstatic character of the geometry be-yond the horizon. Edery - Constantineau prescription is used t...

We study the thermodynamic properties of horizons using the dynamical description of the grav-
itational degrees of freedom at a horizon given in [4]. We use the action of the horizon degrees of free...

In the context of averaging an inhomogeneous cosmological model, we propose a natural measure identical to the Kullback-Leibler relative information entropy, which expresses the distinguishability of ...
Entropy of extremal black holes from entropy of quasiblack holes

2010/12/20
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...
Correspondence between entropy-corrected holographic and Gauss-Bonnet dark energy models
Correspondence between entropy-corrected holographic Gauss-Bonnet dark energy models
font style='font-size:12px;'>
2010/12/20
In the present work we investigate the cosmological implications of the entropy-corrected
holographic dark energy (ECHDE) density in the Gauss-Bonnet framework. This is motivated
from the loop quant...

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...

In any static spacetime the quasilocal Tolman mass contained within a volume can be reduced to a Gauss-like surface integral involving the flux of a suitably defined generalized surface gravity. By in...
