Strings near a Rindler or black hole horizon.
Orbifold techniques are used to study bosonic, type II and heterotic strings in Rindler space at integer multiples N of the Rindler temperature, and near a black hole horizon at integer multiples of the Hawking temperature, extending earlier results of Dabholkar. It is argued that a Hagedorn transition occurs nears the horizon for all N > 1.
متن کاملShock-wave cosmology inside a black hole.
We construct a class of global exact solutions of the Einstein equations that extend the Oppeheimer-Snyder model to the case of nonzero pressure, inside the black hole, by incorporating a shock wave at the leading edge of the expansion of the galaxies, arbitrarily far beyond the Hubble length in the Friedmann-Robertson-Walker (FRW) spacetime. Here the expanding FRW universe emerges be-hind a su...
متن کاملThe Exact String Black - Hole behind the hadronic Rindler horizon ?
The recently suggested interpretation [1] of the universal hadronic freeze-out temperature T f (≃ 170 Mev) – found for all high energy scattering processes that produce hadrons: e + e − , pp, p¯ p, πp, etc. and N N ′ (heavy-ion collisions) – as a Unruh temperature triggers here the search for the gravitational black-hole that in its near-horizon approximation better simulates this hadronic phen...

متن کاملGeometry of Black Hole Thermodynamics
The Hessian of the entropy function can be thought of as a metric tensor on the state space. In the context of thermodynamical fluctuation theory Ruppeiner has argued that the Riemannian geometry of this metric gives insight into the underlying statistical mechanical system; the claim is supported by numerous examples. We study this geometry for some families of black holes. It is flat for the ...
