Quantization in black hole backgrounds
Quantum field theory in a semiclassical background can be derived as an approximation to quantum gravity from a weak-coupling expansion in the inverse Planck mass. Such an expansion is studied for evolution on “nice-slices” in the spacetime describing a black hole of mass M. Arguments for a breakdown of this expansion are presented, due to significant gravitational coupling between fluctuations...
متن کاملBlack Hole Area Quantization *
It has been argued by several authors that the quantum mechanical spectrum of black hole horizon area must be discrete. This has been confirmed in different formalisms, using different approaches. Here we concentrate on two approaches, the one involving quantization on a reduced phase space of collective coordinates of a Black Hole and the algebraic approach of Bekenstein. We show that for non-...
متن کاملBlack hole entropy quantization.
Ever since the pioneering works of Bekenstein and Hawking, black hole entropy has been known to have a quantum origin. Furthermore, it has long been argued by Bekenstein that entropy should be quantized in discrete (equidistant) steps given its identification with horizon area in (semi-)classical general relativity and the properties of area as an adiabatic invariant. This lead to the suggestio...
متن کاملBaryon vertices in AdS black hole backgrounds
Although string theory was originally constructed for the purpose of describing the behavior of quarks in hadrons, it has been developed for long time independently of hadron physics as a possible form for a theory unifying gravity and other interactions, because it can be formulated only in 10 or 26 spacetime dimensions, and spin 2 massless particles arise naturally. The scale of the fundament...
متن کاملStrichartz Estimates on Schwarzschild Black Hole Backgrounds
We study dispersive properties for the wave equation in the Schwarzschild space-time. The rst result we obtain is a local energy estimate. This is then used, following the spirit of [29], to establish global-in-time Strichartz estimates. A considerable part of the paper is devoted to a precise analysis of solutions near the trapping region, namely the photon sphere.
