Hawking equation
WebWe review some aspects of our longstanding research concerning the analogous Hawking effect in dispersive dielectric media. We introduce nonlinear contributions in the polarization field in the relativistically covariant version of the Hopfield model and then, in order to provide a simplified description aimed at avoiding some subtleties in the quantization of … WebMay 2, 2024 · The new Hawking-Hertog assessment indicates that there can only be universes that have the same laws of physics as our own. That conjecture means that our Universe is typical and so observations...

WebOct 1, 2024 · With the help of radiation power expression, one can compute total energy emitted as Hawking radiation by multiplying the power with black hole evaporation time scale and this must be equal to the total mass of the black hole by virtue of energy conservation. This may provide an insight to the process of black hole evaporation. WebNov 8, 2024 · I want to calculate the Hawking temperature of the metric d s 2 = − ( 1 − r 2 l 2) d t 2 + d r 2 ( 1 − r 2 l 2) + r 2 d x 2. Since the metric is diagonal, I guess the Hawking formula for the temperature of this metric isn't complicated. Do you know how one can calculate the temperature?
