Quantum Radiation of a Uniformly Accelerated Refractive Body
نویسنده
چکیده
We study quantum radiation generated by an accelerated motion of a small body with a refractive index n which differes slightly from 1. To simplify calculations we consider a model with a scalar massless field. We use the perturbation expansion in a small parameter n − 1 to obtain a correction to the vacuum Hadamard function for a uniformly accelerated motion of the body. We obtain the vacuum expectation for the energy density flux in the wave zone and discuss its properties.

Quantum field and uniformly accelerated oscillator
We present an exact treatment of the influences on a quantum scalar field in its Minkowski vacuum state induced by coupling of the field to a uniformly accelerated harmonic oscillator. We show that there are no radiation from the oscillator in the point of view of a uniformly accelerating observer. On the other hand, there are radiations in the point of view of an inertial observer. It is shown...
متن کاملComment on " Vanishing Hawking Radiation from a Uniformly
We argue that the analysis of transients, of decoherence effects, or of any breaking of the exact boost invariance of the Ernst metric shows that uniformly accelerated black holes do emit an energy flux given by the Doppler-shifted Hawking radiation, in perfect agreement to what happens for accelerated particles.
متن کامل0 Is there emitted radiation in Unruh effect ?
The thermal radiance felt by a uniformly accelerated detector/oscillator/atom– the Unruh effect [1] – is often mistaken to be some emitted radiation detectable by an observer/probe/sensor. Here we show by an explicit calculation of the energy momentum tensor of a quantum scalar field that, at least in 1+1 dimension, while a polarization cloud is found to exist around the particle trajectory, th...
متن کاملQuantum Radiation of Uniformly Accelerated Spherical Mirrors
We study quantum radiation generated by a uniformly accelerated motion of small spherical mirrors. To obtain Green’s function for a scalar massless field we use Wick’s rotation. In the Euclidean domain the problem is reduced to finding an electric potential in 4D flat space in the presence of a metallic toroidal boundary. The latter problem is solved by a separation of variables. After performi...
متن کاملHawking-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]...
