Unruh acceleration radiation revisited

The Unruh effect revisited

We give a complete and rigorous proof of the Unruh effect, in the following form. We show that the state of a two-level system, uniformly accelerated with proper acceleration a, and coupled to a scalar bose field initially in the Minkowski vacuum state will converge, asymptotically in the detector’s proper time, to the Gibbs state at inverse temperature β = 2π a . The result also holds if the f...

Unruh Radiation via WKB Method

Unruh Radiation with Ultra - Intense Lasers ?

ABSTRACT We point out that using the state-of-the-art (or soon-to-be) intense ultrafast laser technology, violent acceleration that may be suitable for testing general relativistic e ects can be realized through the interaction of a high intensity laser with a plasma. In particular, we demonstrate that the Unruh radiation is detectable, in principle, beyond the conventional radiation (most nota...

Hawking-Unruh Radiation and Radiation of a Uniformly Accelerated Charge

Hawking-Unruh radiation is a measure of the quantum fluctuations in the radiation of accelerated charges. In the case of uniform acceleration, the existence of Unruh radiation adds confidence that radiation exists at all, and helps clarify aspects of the equivalence between radiation in uniform acceleration and in a uniform gravitational field. 1 Hawking-Unruh Radiation According to Hawking [1]...

On Hawking/Unruh Process: Where does the Radiation Come from?

The energy source of the radiation in Unruh/Hawking process is investigated with emphasis on the particle number definition based on conservation laws. It has been shown that the particle radiation is not the result of pair creation by the gravitational force, but the result of difference in the conservation laws to define the particle number. The origin of the radiated energy in the distant fu...
