Coarse-graining of bubbling geometries and the fuzzball conjecture
In the LLM bubbling geometries, we compute the entropies of black holes and estimate their “horizon” sizes from the fuzzball conjecture, based on coarse-graining on the gravity side. The differences of black hole microstates cannot be seen by classical observations. Conversely, by counting the possible deformations of the geometry which are not classically detectable, we can calculate the entro...
متن کاملCoarse-graining 1/2 BPS geometries of type IIB supergravity
Recently Lin, Lunin and Maldacena (LLM) [1] explicitly mapped 1/2 BPS excitations of type IIB supergravity on AdS5×S into free fermion configurations. We discuss thermal coarse-gaining of LLM geometries by explicitly mapping the corresponding equilibrium finite temperature fermion configuration into supergravity. Following Mathur conjecture, a prescription of this sort should generate a horizon...

متن کاملCoarse graining
Multiscale simulations For nearly all systems of interest to us, the most transferrable and fundamental description of matter is one that invokes quantum mechanics. At the highest level of accuracy, this amounts to solving Schrodinger’s equation for all of the subatomic particles in a system. Computationally, many approximations need to be made in order to use ab initio methods, and even these ...
متن کاملPredictive coarse-graining
Brute-force molecular dynamics simulations are limited by the exuberant number of degrees of freedom and the relatively small time-steps. As a result, only relatively small assemblies of molecules over small time spans are accessible with current and foreseeable computational capabilities. In order to overcome this limitation, coarse-grained models have been proposed which employ a much smaller...
