چکیده

It has been 30 years since the discovery of the Unruh effect. It has played a crucial role in our understanding that the particle content of a field theory is observer dependent. This effect is important in its own right and as a way to understand the phenomenon of particle emission from black holes and cosmological horizons. The Unruh effect is reviewed here with particular emphasis on its applications. A number of recent developments are also commented on and some controversies are discussed. Effort is also made to clarify what seem to be common misconceptions.

Applications of Geometric Algebra to Physics: Theoretical Framework, Cosmological Hawking Radiation and Unruh Effect

We discuss the applications of Gauge Theory Gravity (GTG) within the language of geometric algebra to the Dirac equation in the de Sitter and Rindler metrics as well as to the Unruh effect. We rederive the Hawking temperature for each case. The derivation of both the correct Fermi-Dirac statistics as well as the Hawking temperature may suggest that the method of calculations we employ here geom...

Using Berry's phase to detect the Unruh effect at lower accelerations.

We show that a detector acquires a Berry phase due to its motion in spacetime. The phase is different in the inertial and accelerated case as a direct consequence of the Unruh effect. We exploit this fact to design a novel method to measure the Unruh effect. Surprisingly, the effect is detectable for accelerations 10(9) times smaller than previous proposals sustained only for times of nanoseconds.

Tabletop creation of entangled multi-keV photon pairs and the Unruh effect.

Electrons moving in a strong periodic electromagnetic field (e.g., laser or undulator) may convert quantum vacuum fluctuations into pairs of entangled photons, which can be understood in terms of the Unruh effect. Apart from verifying this striking phenomenon, the considered effect may allow the construction of a tabletop source for entangled photons ("photon pair laser") and the associated qua...

The Schwinger Mechanism, the Unruh Effect and the Production of Accelerated Black Holes

We prove that the Heisenberg-Euler-Schwinger mechanism –pair creation in a constant electric field– and its radiative corrections imply the Unruh effect, i.e. the thermalisation of accelerated systems at temperature a/2π where a is the acceleration. More precisely, the properties of the amplitudes for pair creation under crossing symmetry and CPT are sufficient to deduce the Unruh effect. Furth...

Kaluza-Klein reduction for the Unruh brane

We present a Kaluza-Klein reduction for the Unruh response that a brane, in an AdS bulk would experience due to its acceleration. The Unruh radiation is realised as particle production on the brane for each of the Kaluza-Klein modes. A correction, coming from the massive modes, is calculated for the standard Unruh effect in Minkowski spacetime and it is found that the response coming from these...
