Hawking fragmentation and Hawking attenuation in Weyl semimetals

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...

Hawking 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...

Hawking radiation and ultraviolet regulators.

Polchinski has argued that the prediction of Hawking radiation must be independent of the details of unknown high-energy physics because the calculation may be performed using ‘nice slices’, for which the adiabatic theorem may be used. If this is so, then any calculation using a manifestly covariant — and so slice-independent — ultraviolet regularization must reproduce the standard Hawking resu...
