0 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 کاملThere is no “ first ” quantization
The appearance of spinor fields as operators or arguments of field functionals in quantum field theory is often regarded as a second quantization, since fermion wave functions were themselves discovered by quantizing mass points (" particles "). I argue that this language, though reflecting the historical development, is misleading. Field amplitudes always represent the true physical variables ...
متن کاملUnruh Effect in Storage Rings
A uniformly accelerated system will get thermally excited due to interactions with the vacuum fluctuations of the quantum fields. This is the Unruh effect. Also a system accelerated in a circular orbit will be heated, but in this case complications arise relative to the linear case. An interesting question is in what sense the real quantum effects for orbital and spin motion of a circulating el...
متن کاملThe 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...
متن کاملThe Fulling-Davies-Unruh Effect is Mandatory: The Proton’s Testimony
We discuss the decay of accelerated protons and illustrate how the FullingDavies-Unruh effect is indeed mandatory to maintain the consistency of standard Quantum Field Theory. The confidence level of the Fulling-Davies-Unruh effect must be the same as that of Quantum Field Theory itself.
