Gravitational statistical mechanics: A model

  title={Gravitational statistical mechanics: A model},
  author={Seth A. Major and Kevin L. Setter},
  journal={Classical and Quantum Gravity},
Using the quantum Hamiltonian for a gravitational system with boundary, we find the partition function and derive the resulting thermody- namics. The Hamiltonian is the boundary term required by functional differ- entiability of the action for Lorentzian general relativity. In this model, states of quantum geometry are represented by spin networks. We show that the statistical mechanics of the model reduces to that of a simple non-interacting gas of particles with spin. Using both canonical and… Expand

On a Scale-Invariant Model of Statistical Mechanics and the Laws of Thermodynamics
A scale-invariant model of statistical mechanics is applied to describe modified forms of zeroth, first, second, and third laws of classical thermodynamics. Following Helmholtz, the total thermalExpand
Semiclassical Length Measure from a Quantum-Gravity Wave Function
The definition of a length operator in quantum cosmology is usually influenced by a quantum theory for gravity considered. The semiclassical limit at the Planck age must meet the requirements impliedExpand
Thermal Fluctuations and Black Hole Entropy
In this paper, we consider the effect of thermal fluctuations on the entropy of both neutral and charged black holes. We emphasize the distinction between fixed and fluctuating charge systems; usingExpand
A dynamical evolution model on the black-hole horizon
This paper demonstrates a dynamical evolution model of the black-hole (BH) horizon. The result indicates that a kinetic area-cell model of the BH horizon can model the evolution of the BH due to theExpand
Entropy corrections for Schwarzschild and Reissner-Nordstrom black holes
A Schwarzschild black hole being thermodynamically unstable, corrections to its entropy due to small thermal fluctuations cannot be computed. However, a thermodynamically stable SchwarzschildExpand
On the universality of the entropy-area relation
We present an argument that for a large class of possible dynamics, a canonical quantization of gravity will satisfy the Bekenstein–Hawking entropy–area relation. This result holds for temperaturesExpand
Anti-de Sitter black holes, perfect fluids, and holography
We consider asymptotically anti-de Sitter black holes in d-spacetime dimensions in the thermodynamically stable regime. We show that the Bekenstein–Hawking entropy and its leading order correctionsExpand
Entropy Correction for Kerr Black Hole
In this paper, we discuss leading-order corrections to the entropy of Kerr black hole due to thermal fluctuations in the finite cavity. Then temperature is constant, the solution of the black hole isExpand
Logarithmic correction to the Brane equationin topological Reissner-Nordström de Sitter space
Abstract.In this paper we study braneworld cosmology when the bulk space is a charged black hole in de Sitter space (topological Reissner-Nordström de Sitter Space) in a general number of dimensions;Expand
A comment on black hole entropy or does nature abhor a logarithm
There has been substantial interest, as of late, in the quantum-corrected form of the Bekenstein–Hawking black hole entropy. The consensus viewpoint is that the leading-order correction should be aExpand


On Quantum Statistical Mechanics of a Schwarzschild Black Hole
Quantum theory of geometry, developed recently in the framework of non-perturbative quantum gravity, is used in an attempt to explain thermodynamics of Schwarzschild black holes on the basis of aExpand
Counting surface states in the loop quantum gravity
We adopt the point of view that (Riemannian) classical and (loopbased) quantum descriptions of geometry are macroand micro-descriptions in the usual statistical mechanical sense. This gives rise toExpand

A general form of the first law of thermodynamics for stationary black holes is derived and the density of states is expressed as a real-time functional integral and then used to deduce Feynman's imaginary- time functional integral for the canonical partition function. Expand

A new functional calculus, developed recently for a fully non-perturbative treatment of quantum gravity, is used to begin a systematic construction of a quantum theory of geometry. RegulatedExpand

Abstract We study the operator that corresponds to the measurement of volume, in non-perturbative quantum gravity, and we compute its spectrum. The operator is constructed in the loop representation,Expand

The reduced Lorentzian Hamiltonian is shown to contain two independent terms, one from the timelike boundary and the other from the bifurcation two-sphere, which gives rise to the black hole entropy in a way that is related to the Euclidean variational problem. Expand
