Kerr Black hole mimickers sourced by a string fluid
Ram Brustein, A. J. M. Medved, Tamar Simhon
We present rotating solutions of Einstein's gravity coupled to an effective Born-Infeld theory that describes the end of open-string tachyon condensation after the decay of an unst…
Thermodynamics of frozen stars
Ram Brustein, A. J. M. Medved, Tamar Simhon
The frozen star is a recent proposal for a non-singular solution of Einstein's equations that describes an ultracompact object which closely resembles a black hole from an external…
A correspondence between strings in the Hagedorn phase and asymptotically de Sitter space
Ram Brustein, A. J. M. Medved
A correspondence between closed strings in their high-temperature Hagedorn phase and asymptotically de Sitter (dS) space is established. We identify a thermal, conformal field theo…
Realistic clocks for a Universe without time
K. L. H. Bryan, A. J. M. Medved
There are a number of problematic features within the current treatment of time in physical theories, including the "timelessness" of the Universe as encapsulated by the Wheeler-De…
The ratio of shear viscosity to entropy density in generalized theories of gravity
Ram Brustein, A. J. M. Medved
Near the horizon of a black brane solution in Anti-de Sitter space, the long-wavelength fluctuations of the metric exhibit hydrodynamic behaviour. For Einstein's theory, the ratio…
