Real vacuum fluctuations and virtual Unruh radiation
A straightforward dynamical and statistical analysis of the blackbody radiation field, including the zero‐point component, serves to disclose the key elements leading to Planck's spectral
Quantum optics of an oscillator falling into a black hole
We present a quantum optics treatment of the near horizon behaviour of a quantum oscillator freely-falling into a pre-existing Schwarzschild black hole. We use Painlevé–Gullstrand coordinates to
Laboratory soft x-ray emission due to the Hawking–Unruh effect?
The structure of spacetime, quantum field theory, and thermodynamics are all connected through the concepts of the Hawking and Unruh temperatures. The possible detection of the related radiation
Fluctuation and inertia
Demise of Unruh radiation
Unruh radiation has attracted much interest, particularly because of its relationship to Hawking radiation. But its existence has been challenged by a variety of authors, including ourselves [Phys.
Unruh effect and the concept of temperature
Based on a discussion of the concepts of temperature, passivity and efficiency in the framework of quantum field theory, the physical interpretation of the Unruh effect is reviewed.
Generalization of the Schott energy in electrodynamic radiation theory
We discuss the origin of the Schott energy in the Abraham-Lorentz version of electrodynamic radiation theory and how it can be used to explain some apparent paradoxes. We also derive the
Unruh effect and information flow
We study memory effects as information backflow for an accelerating two-level detector weakly interacting with a scalar field in the Minkowski vacuum. This is the framework of the well-known Unruh
Near-horizon aspects of acceleration radiation by free fall of an atom into a black hole
A two-level atom freely falling towards a Schwarzschild black hole was recently shown to detect radiation in the Boulware vacuum in an insightful paper [M. O. Scully et al., Proc. Natl. Acad. Sci.

Does a quantum system, with no long-range interaction, which is uniformly accelerated through the Minkowski vacuum radiate as a result of excitation by the Unruh-Davies heat bath ? We address this

The Minkowski vacuum state is a thermal state as far as any uniformly accelerated observer is concerned. However, if we allow a thermal bath, or any system to come to equilibrium with that thermal

The theory is used here to show that a detector with a uniform acceleration will respond to its own self-field as if immersed in a thermal photon bath at temperature {ital T}{sub {ital a}}={h bar}a/2{pi}kc}, and this process gives rise to the appearance of a photon bath.
Unruh effect with back reaction-A first-quantized treatment
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. {copyright}
Enhancing acceleration radiation from ground-state atoms via cavity quantum electrodynamics.
When ground-state atoms are accelerated through a high Q microwave cavity, radiation is produced with an intensity which can exceed the intensity of Unruh acceleration radiation in free space by many
Scalar production in Schwarzschild and Rindler metrics
The procedure used recently by Hawking (1975) to demonstrate the creation of massless particles by black holes is applied to the Rindler coordinate system in flat space-time. The result is that an
Testing Unruh Radiation with Ultraintense Lasers
We point out that using the state-of-the-art (or soon-to-be) intense electromagnetic pulses, violent accelerations that may be suitable for testing quantum field theory in curved spacetime can be
Quantum Langevin equation.
It is shown that the most general quantum Langevin equation can be realized by this simple model and a critical comparison is made with a number of other models that have appeared in the literature.
Bremsstrahlung and Fulling-Davies-Unruh thermal bath.
It is shown that the emission of a photon from the source as described by the inertial observer can be interpreted the accelerated frame as either the emission or the absorption of a zero-energy Rindler photon in the thermal bath.
