Hawking Radiation and Hawking Flux from Spherical Reduction
Hawking radiation in D = 4 is regarded as a well-understood quantum theoretical feature of black holes (BH) or of other geometric backgrounds with an event horizon. On the other hand, the dilaton theory emerging after spherical reduction from Einstein gravity (SRG) and generalizations of those theories, only during the last years have been investigated in this connection. If the consideration o...
متن کاملHawking Radiation from Decoherence
It is argued that the thermal nature of Hawking radiation arises solely due to decoherence. Thereby any information-loss paradox is avoided because for closed systems pure states remain pure. The discussion is performed for a massless scalar field in the background of a Schwarzschild black hole, but the arguments should hold in general. The result is also compared to and contrasted with the sit...
متن کاملHawking Radiation from Feynman Diagrams
The aim of this letter is to clarify the relationships between Hawking radiation and the scattering of light by matter falling into a black hole. To this end we analyze the S-matrix elements of a model composed of a massive infalling particle (described by a quantized field) and the radiation field. These fields are coupled by current-current interactions and propagate in the Schwarzschild geom...
متن کاملFrom Motzkin to Catalan permutations
For every integer j¿1, we de ne a class of permutations in terms of certain forbidden subsequences. For j = 1, the corresponding permutations are counted by the Motzkin numbers, and for j =∞ (de ned in the text), they are counted by the Catalan numbers. Each value of j¿ 1 gives rise to a counting sequence that lies between the Motzkin and the Catalan numbers. We compute the generating function ...
متن کاملHawking Temperature from Quasi-normal Modes
A perturbed black hole has characteristic frequencies (quasi-normal modes). Here I apply a quantum measurement analysis of the quasinormal mode frequency in the limit of high damping. It turns out that a measurement of this mode necessarily adds noise to it. For a Schwarzschild black hole, this corresponds exactly to the Hawking temperature. The situation for other black holes is briefly discus...
