Prospecting black hole thermodynamics with fractional quantum mechanics
نویسندگان
چکیده
This paper investigates whether the framework of fractional quantum mechanics can broaden our perspective black hole thermodynamics. Concretely, we employ a {\it space-fractional} derivative \cite{Rie} as main tool. Moreover, restrict analysis to case Schwarzschild configuration. From subsequently modified Wheeler-DeWitt equation, retrieve corresponding expressions for specific observables. Namely, mass spectrum, $M$, its temperature $T$, and entropy, $S$. We find that these bear consequential alterations conveyed through parameter, $\alpha$. In particular, standard results are recovered in limit $\alpha=2$. Furthermore, elaborate how generalizations entropy-area relation suggested by Tsallis Cirto \cite{Tsallis} Barrow \cite{Barrow} acquire complementary interpretation terms point view. A thorough discussion is presented.

Statistical Mechanics and Black Hole Thermodynamics
Black holes are thermodynamic objects, but despite recent progress, the ultimate statistical mechanical origin of black hole temperature and entropy remains mysterious. Here I summarize an approach in which the entropy is viewed as arising from “would-be pure gauge” degrees of freedom that become dynamical at the horizon. For the (2+1)-dimensional black hole, these degrees of freedom can be cou...
متن کاملThe Statistical Mechanics of Black Hole Thermodynamics *
Although we have convincing evidence that a black hole bears an entropy proportional to its surface (horizon) area, the “statistical mechanical” explanation of this entropy remains unknown. Two basic questions in this connection are: what is the microscopic origin of the entropy, and why does the law of entropy increase continue to hold when the horizon entropy is included? After a review of so...
متن کاملBlack hole entropy: statistical mechanics agrees thermodynamics
We discuss the connection between different entropies introduced for black hole. It is demonstrated on the two-dimensional example that the (quantum) thermodynamical entropy of a hole coincides (including UV-finite terms) with its statisticalmechanical entropy calculated according to ’t Hooft and regularized by Pauli-Villars.

متن کاملBlack Hole Thermodynamics from Quantum Gravity ∗
The semiclassical approximation is studied on hypersurfaces approaching the union of future null infinity and the event horizon on a large class of four dimensional black hole backgrounds. Quantum fluctuations in the background geometry are shown to lead to a breakdown of the semiclassical approximation in these models. The boundary of the region where the semiclassical approximation breaks dow...
متن کاملQuantum Thermodynamics of Black Hole Horizons
Exploiting results recently proved in a technical paper (and some of them are reviewed herein in the language of theoretical physicists) we focus on quantization of the metric of a black hole restricted to the Killing horizon with universal radius r0. The metric is represented in a suitable manner after imposing spherical symmetry and, after restriction to the Killing horizon, it is quantized e...
