Gravity coupling from micro-black holes
نویسنده
چکیده
Recently much work has been done in lowering the Planck threshold of quantum gravitational effects (sub-millimeter dimension(s), Horava-Witten fifth dimension, strings or branes low energy effects, etc.). With a semi-classical calculation based on Hawking evaporation of planckian micro-black holes, I shall show in this paper as quantum gravity effects have to be present also at GUT energies.

Black holes with a null Killing vector in three-dimensional massive gravity
We investigate solutions of new massive gravity with two commuting Killing vectors, one of which is null, with a special emphasis on black hole solutions. Besides extreme BTZ black holes and, for a special value of the coupling constant, massless null warped black holes, we also obtain for a critical coupling a family of massive “log” black holes. These are asymptotic to the extreme BTZ black h...

متن کاملThe phase transition of corrected black hole with f(R) gravity
In this letter, we consider static black hole in f(R) gravity.We take advantage from corrected entropy and temperature and investigate such black hole. Finally, we study the $ P - V $ critically and phase transition of corrected black hole with respect to entropy and temperature. Here also, we obtain the heat capacity for the static black hole in $ f(R) $ gravity. This calculation help us...
متن کاملNature of Microscopic Black Holes and Gravity in Theories with Particle Species
Relying solely on unitarity and the consistency with large-distance black hole physics, we derive model-independent properties of the microscopic black holes and of shortdistance gravity in theories with N particle species. In this class of theories black holes can be as light as MP lanck/ √ N and be produced in particle collisions above this energy. We show, that the micro black holes must com...
متن کاملA bound on the effective gravitational coupling from semiclassical black holes
We show that the existence of semiclassical black holes of size as small as a minimal length scale lUV implies a bound on a gravitational analogue of ’t-Hooft’s coupling λG(l) ≡ N(l)GN/l at all scales l ≥ lUV . The proof is valid for any metric theory of gravity that consistently extends Einstein’s gravity and is based on two assumptions about semiclassical black holes: i) that they emit as bla...
