Unifying The Tunneling And Anomaly Phenomena In Hawking Radiation
In this Letter we have derived the gravitational anomaly leading to the Hawking radiation from a fundamentally different perspective: it emerges due to the complimentary roles played by tunneling and (gravitational) anomaly. We have used the analogy of an early idea [6] of visualizing chiral gauge anomaly as an effect of spectral flow of the energy levels, from the negative energy Dirac sea, ac...
متن کاملHawking Radiation from General Kerr-(anti)de Sitter Black Holes
We calculate the total flux of Hawking radiation from Kerr-(anti)de Sitter black holes by using gravitational anomaly method developed in [6]. We consider the general Kerr(anti)de Sitter black holes in arbitrary D dimensions with the maximal number [D/2] of independent rotating parameters. We find that the physics near the horizon can be described by an infinite collection of (1 + 1)-dimensiona...
متن کاملHawking Radiation ∗
It is shown in a variant of two dimensional dilaton gravity theories that an arbitrary , localized massive source put in an initially regular spacetime gives rise to formation of the wormhole classically, without accompanying the curvature singu-larity. The semiclassical quantum correction under this wormhole spacetime yields Hawking radiation. It is expected, with the quantum back reaction add...
متن کاملHawking 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 کاملHartle-Hawking Wave Function
In most attempts to compute the Hartle-Hawking “wave function of the universe” in Euclidean quantum gravity, two important approximations are made: the path integral is evaluated in a saddle point approximation, and only the leading (least action) extremum is taken into account. In (2+1)dimensional gravity with a negative cosmological constant, the second assumption is shown to lead to incorrec...
