Exact Microscopic Entropy of Non-Supersymmetric Extremal Black Rings
Roberto Emparan
In this brief note we show that the horizon entropy of the largest known class of non-supersymmetric extremal black rings, with up to six parameters, is exactly reproduced for all…
Fundamental Plasmid Strings and Black Rings
Jose J. Blanco-Pillado, Roberto Emparan, Alberto Iglesias
We construct excited states of fundamental strings that admit a semiclassical description as rotating circular loops of string. We identify them with the supergravity solutions for…
Microscopic Theory of Black Hole Superradiance
Oscar J. C. Dias, Roberto Emparan, Alessandro Maccarrone
We study how black hole superradiance appears in string microscopic models of rotating black holes. In order to disentangle superradiance from finite-temperature effects, we consid…
Statistical Description of Rotating Kaluza-Klein Black Holes
Roberto Emparan, Alessandro Maccarrone
We extend the recent microscopic analysis of extremal dyonic Kaluza-Klein (D0-D6) black holes to cover the regime of fast rotation in addition to slow rotation. Fastly rotating bla…
Black Hole Production at a TeV
Roberto Emparan
In this talk I briefly discuss some features of a striking signature of TeV quantum gravity/strings and large extra dimensions: the production of exotic objects such as black holes…
