Black hole radiation in the presence of a short distance cutoff.
A derivation of the Hawking effect is given which avoids reference to field modes above some cutoff frequency ωc ≫ M−1 in the freefall frame of the black hole. To avoid reference to arbitrarily high frequencies, it is necessary to impose a boundary condition on the quantum field in a timelike region near the horizon, rather than on a (spacelike) Cauchy surface either outside the horizon or at e...
متن کاملInformation in black hole radiation.
If black hole formation and evaporation can be described by an S matrix, information would be expected to come out in black hole radiation. An estimate shows that it may come out initially so slowly, or else be so spread out, that it would never show up in an analysis perturbative in MP lanck/M , or in 1/N for two-dimensional dilatonic black holes with a large number N of minimally coupled scal...
متن کاملAnalytic Black Hole Perturbation Approach to Gravitational Radiation
We review the analytic methods used to perform the post-Newtonian expansion of gravitational waves induced by a particle orbiting a massive, compact body, based on black hole perturbation theory. There exist two different methods of performing the post-Newtonian expansion. Both are based on the Teukolsky equation. In one method, the Teukolsky equation is transformed into a Regge-Wheeler type eq...
متن کاملModified dispersion relations and black hole physics
A modified formulation of energy-momentum relation is proposed in the context of doubly special relativity. We investigate its impact on black hole physics. It turns out that such modification will give corrections to both the temperature and the entropy of black holes. In particular this modified dispersion relation also changes the picture of Hawking radiation greatly when the size of black h...
متن کاملA Matrix-Model Black Hole
In this paper the c = 1 matrix model deformed by a 1/x piece is discussed. Tachyon correlation functions are calculated up to genus two using methods similar to those for the undeformed case. The possible connection with the two dimensional black hole is also considered. In particular, restrictions on naked singularities imposed by the matrix model are found. CERN-TH.6916/93 June 1993
