# Black Hole Entropy and Gravity Cutoff

@article{Dvali2008BlackHE, title={Black Hole Entropy and Gravity Cutoff}, author={Gia Dvali and Sergey N. Solodukhin}, journal={arXiv: High Energy Physics - Theory}, year={2008} }

We study the black hole entropy as entanglement entropy and propose a resolution to the species puzzle. This resolution comes out naturally due to the fact that in the presence of $N$ species the universal gravitational cutoff is $\Lambda=M_{\rm Planck}/\sqrt{N}$, as opposed to $M_{\rm Planck}$. We demonstrate consistency of our solution by showing the equality of the two entropies in explicit examples in which the relation between $M_{\rm Planck}$ and $\Lambda$ is known from the fundamental…

Bounds on black hole entropy in unitary theories of gravity

We consider unitary and weakly coupled theories of gravity that extend Einstein gravity and reduce to it asymptotically at large distances. Our discussion is restricted to such theories that,…

Based on well-known properties of semi-classical black holes, we show that weakly-coupled string theory can be viewed as a theory of N = 1/g_s^2 particle species. This statement is a string theoretic…

The focus in the review is on the systematic use of the conical singularity method and the puzzling behavior of the entanglement entropy due to fields, which non-minimally couple to gravity, which is illustrated on two- and four-dimensional examples.

Unitarity implies that the evaporation of microscopic quasiclassical black holes cannot be universal in different particle species. This creates a puzzle, since it conflicts with the thermal nature…

We present an evidence, that the volumes of compactified spaces as well as the areas of black hole horizons must be quantized in Planck units. This quantization has phenomenological consequences,…
