Derivation of hawking temperature
WebHawking temperature of a black hole can be approx-imated from the values of the constants as T 1 M 023; this is only about 10-7K12above absolute zero even for the … WebSep 1, 2024 · In the next section, we obtain the analytical Hawking temperature for general velocity profiles z ± 1 ∕ n (sonic) and τ ± 1 ∕ n (optical). Two formulas for sonic analogs derived in Ref. [20] are included as particular cases, including the Schwarzschild spacetime, but the rest are new analytical results from this work. We also develop an equation for a …

The aim of this paper is to present a simple heuristic derivation of the Hawking temperature, based on the Heisenberg uncertainty principle.
WebJun 7, 2024 · Stephen Hawking's most important scientific contribution was his theoretical demonstration that black holes (BHs) are not really black after all, since they produce a thermal emission, the Hawking radiation, and therefore have a characteristic temperature known as Hawking temperature.
WebThe brick wall method is a semi-classical approach, where the BH is considered as a fixed background that is in thermal equilibrium with a thermal bath of some surrounding quantum matter fields at the Hawking temperature. Therefore, the canonical entropy of the matter field outside the BH horizon is related to the entropy of BH itself. razer reset mouseWebJun 3, 2024 · Deriving Hawking temperature "from" Unruh effect and their relation.
