A WKB-like approach to Unruh Radiation
Andrea de Gill, Douglas Singleton, Valeria Akhmedova +1
Unruh radiation is the thermal flux seen by an accelerated observer moving through Minkowski spacetime. In this article we study Unruh radiation as tunneling through a barrier. We…
Quasi-classical Hawking Temperatures and Black Hole Thermodynamics
Terry Pilling
The semi-classical derivation of Hawking radiation for axially symmetric, stationary spacetimes with a Killing horizon is examined following the recent quasi-classical tunneling an…
Comments on anomaly versus WKB/tunneling methods for calculating Unruh radiation
Valeria Akhmedova, Terry Pilling, Andrea de Gill +1
In this Letter we make a critique of, and comparison between, the anomaly method and WKB/tunneling method for obtaining radiation from non-trivial spacetime backgrounds. We focus o…
Dark Entropy
Richard T Hammond, Terry Pilling
We examine the consequences of a universe with a non-constant cosmological term in Einstein's equations and find that the Bianchi identities reduce to the first law of thermodynami…
Subtleties in the quasi-classical calculation of Hawking radiation
Emil T. Akhmedov, Terry Pilling, Douglas Singleton
he quasi-classical method of deriving Hawking radiation is investigated. In order to recover the original Hawking temperature one must take into account a previously ignored contri…
Temporal contribution to gravitational WKB-like calculations
Valeria Akhmedova, Terry Pilling, Andrea de Gill +1
Recently, it has been shown that the radiation arising from quantum fields placed in a gravitational background (e.g. Hawking radiation) can be derived using a quasi-classical calc…
