We study the idea that the statistical entropy governing thermal interactions of a black hole with its exterior is determined by the microstates of the hole having distinct effects on the exterior, and over which a hole in a given macroscopic configuration thermally fluctuates. We argue that for a (macroscopically) Schwarzschild black hole this ensemble is formed by horizons with the same area. We compute the number of states in this ensemble from first principles using nonperturbative loop… 
A note on renormalization and black hole entropy in loop quantum gravity
Microscopic state counting for a black hole in loop quantum gravity yields a result proportional to the horizon area, and inversely proportional to Newton's constant and the Immirzi parameter. It is
Black hole entropy and isolated horizons thermodynamics.
Black hole entropy and other thermodynamical quantities can be consistently computed in both ensembles and results are in agreement with Hawking's semiclassical analysis for all values of the Immirzi parameter.
The scaling of black hole entropy in loop quantum gravity
We discuss some general properties of black hole entropy in loop quantum gravity from the perspective of local stationary observers at distance l from the horizon. The present status of the theory
On black hole radiation spectrum in loop quantum gravity
We propose an alternative analysis of black hole entropy from loop quantum gravity (LQG) to reconcile Hawking’s semiclassical results with the statistical mechanics treatment of LQG for all values of
Detailed black hole state counting in loop quantum gravity
The ability to manipulate and understand the spectrum up to the level of detail that is described in the paper is a crucial step towards obtaining the behavior of entropy in the asymptotic (large horizon area) regime.
Black hole entropy, loop gravity, and polymer physics
Loop Gravity provides a microscopic derivation of Black Hole entropy. In this paper, I show that the microstates counted admit a semiclassical description in terms of shapes of a tessellated horizon.
A new explanation for statistical entropy of charged black hole
Using the Unruh-Verlinde temperature obtained by the idea of entropy force, we directly calculated the partition functions of Boson field in Reissner-Nordström spacetime with quantum statistical


Geometry eigenvalues and the scalar product from recoupling theory in loop quantum gravity.
The basics of the loop representation of quantum gravity are summarized and the main aspects of the formalism are described, including its latest developments, in a reorganized and consistent form.
Structural issues in quantum gravity
A discursive, non-technical, analysis is made of some of the basic issues that arise in almost any approach to quantum gravity, and of how these issues stand in relation to recent developments in the
