Title: Effect of a moving mirror on the free fall of a quantum particle in a homogeneous gravitational field
Authors: J. Allam and A. Matzkin
Abstract summary: We investigate the effect of time-dependent boundary conditions on the dynamics of a quantum bouncer -- a particle falling in a homogeneous gravitational field on a moving mirror. We find that some effects, such as the fact that a quantum particle hitting a moving mirror may bounce significantly higher than when the mirror is fixed, are in line with classical intuition.

Abstract: We investigate the effect of time-dependent boundary conditions on the dynamics of a quantum bouncer -- a particle falling in a homogeneous gravitational field on a moving mirror. We examine more particularly the way a moving mirror modifies the properties of the entire wavefunction of a falling particle. We find that some effects, such as the fact that a quantum particle hitting a moving mirror may bounce significantly higher than when the mirror is fixed, are in line with classical intuition. Other effects, such as the change in relative phases or in the current density in spatial regions arbitrarily far from the mirror are specifically quantum. We further discuss how the effects produced by a moving mirror could be observed in link with current experiments, in particular with cold neutrons.

Interference phenomena in the asymmetric dynamical Casimir effect for a single $\delta-\delta^{\prime}$ mirror [0.0]
We consider a real massless scalar field in 1+1 dimensions interacting with a moving $delta-deltaprime$ mirror with time-dependent properties. The asymmetry of the system is investigated by analyzing the difference in particle spectra produced on the two sides of the mirror.

Noise and dissipation on a moving mirror induced by the dynamical Casimir emission [0.0]
We adopt an open quantum system approach to study the dynamics of a moving mirror. We derive the master equation governing the mechanical motion of the mirror. We show that the noise and dissipation kernels, that enter in the definition of the time-dependent coefficients of the master equation, are related by fluctuation-dissipation relations.

Motion induced excitation and electromagnetic radiation from an atom facing a thin mirror [62.997667081978825]
We evaluate the probability of (de-)excitation and photon emission from a neutral, moving, non-relativistic atom, coupled to a quantum electromagnetic field and in the presence of a thin, perfectly conducting plane ("mirror") Results extend to a more realistic model, where the would-be electron was described by a scalar variable, coupled to an (also scalar) vacuum field.

Dynamical Casimir effect enhanced by decreasing the mirror reflectivity [62.997667081978825]
We show that a partially reflecting static mirror with time-dependent properties can produce, via dynamical Casimir effect, a larger number of particles than a perfectly reflecting one. As particular limits, our results recover those found in the literature for a perfect static mirror imposing a generalized or an usual time-dependent Robin boundary condition.

The quantum optics of asymmetric mirrors with coherent light absorption [0.0]
Local observables of the quantised electromagnetic field near a mirror-coated interface depend strongly on the properties of the media on em both sides. We present an alternative, more intuitive approach and obtain the local field observables with the help of a quantum mirror image detector method.

Quantum communication through a partially reflecting accelerating mirror [0.0]
We focus on mirrors that are accelerated via an impulsive force. We realize the field coming from left-past spacetime region, passing through the semitransparent moving mirror. We study the transmission and noisy generation properties of this channel, relating them to the Bogoliubov coefficients of the mirror's motion.

Quantum time dilation in atomic spectra [62.997667081978825]
We demonstrate how quantum time dilation manifests in a spontaneous emission process. The resulting emission rate differs when compared to the emission rate of an atom prepared in a mixture of momentum wave packets. We argue that spectroscopic experiments offer a technologically feasible platform to explore the effects of quantum time dilation.

Zitterbewegung and Klein-tunneling phenomena for transient quantum waves [77.34726150561087]
We show that the Zitterbewegung effect manifests itself as a series of quantum beats of the particle density in the long-time limit. We also find a time-domain where the particle density of the point source is governed by the propagation of a main wavefront. The relative positions of these wavefronts are used to investigate the time-delay of quantum waves in the Klein-tunneling regime.
