We present a first quantized treatment of the back-reaction on an accelerated particle detector. The evaluated transition amplitude for detection agrees with previously obtained results. e-mail: [email protected] 1

We compute the corrections to the transition amplitudes of an accelerated Unruh \box" that arise when the accelerated box is replaced by a \two level ion" immersed in a constant electric eld and treated in second quantization. There are two kinds of corrections, those due to recoil e ects induced by the momentum transfers and those due to pair creation. Taken together, these corrections show th...

Park et al's recent comment that for detectors with large energy gap in comparison with the temperature of the background thermal bath, the maximum excitation rate is obtained for some non-zero detector's velocity is correct but was previously discussed by ourselves in [3], and does not affect in [2] any mathematical formula, numerical result, or our final conclusion that the background thermal...

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...

We study, in the framework of open quantum systems, entanglement dynamics for a system composed two uniformly accelerated Unruh-Dewitt detectors interacting with bath massive scalar fields Minkowski vacuum. find that evolution coupled is always slower compared one massless fields, and this time-delay effect brought by field being can however be counteracted large enough acceleration, contrast t...

We study how the decay properties of particles are changed by acceleration. It is shown that under the influence of acceleration (1) the lifetime of particles is modified and (2) new processes (like the decay of the proton) become possible. This is illustrated by considering scalar models for the decay of muons, pions, and protons. We discuss the close conceptual relation between these processe...

The quantum mechanical evolution of an accelerated extended detector coupled to a massless scalar field is exhibited and the back-reaction due to emission or absorption processes computed at first order in the change of the detector’s mass and acceleration. An analogy with black hole evaporation is found and illustrated. PACS numbers: 03.65.Sq, 04.70.Dy List of keywords: Accelerated observer Ba...
