Some Heuristic Semiclassical Derivations of the Planck Length, the Hawking Effect and the Unruh Effect
نویسنده
چکیده
The formulae for Planck length, Hawking temperature and UnruhDavies temperature are derived by using only laws of classical physics together with the Heisenberg principle put in the form ∆E∆x ≃ h̄c/2. Besides, it is shown how the Hawking relation can be deduced from the Unruh relation by means of the principle of equivalence; the deep link between Hawking effect and Unruh effect is in this way clarified.

Corrections to Unruh effect in tunneling formalism and mapping with Hawking effect
We consider coordinate systems adapted to accelerated observers, construct a generalised Rindler metric and then adopt a specific form of it to compute the semiclassical Unruh temperature, using a WKB approximation within a Hamilton Jacobi analysis in the tunneling picture. Corrections to this temperature are next computed by going beyond the usual WKB approximation. A connection of the correct...
متن کاملShort distances , black holes , and TeV gravity 1
The Hawking effect can be rederived in terms of two-point functions and in such a way that it makes it possible to estimate, within the conventional semiclassical theory, the contribution of ultrashort distances at I to the Planckian spectrum. Thermality is preserved for black holes with κlP ≪ 1. However, deviations from the Planckian spectrum can be found for mini black holes in TeV gravity sc...
متن کاملHawking-like Effects and Unruh-like Effects: toward Experiments ?
The Hawking effect and the Unruh effect are two of the most important predictions in the theoretical physics of the last quarter of the 20th century. In parallel to the theoretical investigations there is great interest in the possibility of revealing effects of this type in some sort of experiments. I present a general discussion of the proposals to measure the Hawking and Unruh effects and/or...
متن کاملRemarks on the Frequency Spectra of Some Fundamental Quantum Effects
Short remarks on the problem of assigning frequency spectra to Casimir, sonoluminescence, Hawking, Unruh, and quantum optical squeezing effects are presented. Introduction Recent years witnessed great progress toward understanding in a quantum field approach the following fundamental quantum effects: Casimir, sonoluminescence, Hawking, Unruh, and squeezing ones. These effects have been treated ...
متن کاملOn the Estimates to Measure Hawking Effect and Unruh Effect in the Laboratory
A comparison between the proposals made to measure Hawking-like effects and the Unruh effect in the laboratory is given at the level of their estimates. No satisfactory scheme exists as yet for their detection.
