- Abstract: We investigate the dynamical Casimir effect for a one-dimensional resonant
cavity, with one oscillating mirror. Specifically, we study the discrete
spectrum of created particles in a region of frequencies above the oscillation
frequency $\omega_0$ of the mirror. We focus our investigation on an
oscillation time equal to $2L_0/c$, where $L_0$ is the initial and final length
of the cavity, and $c$ is the speed of light. For this oscillation duration, a
field mode, after perturbed by the moving mirror, never meets this mirror in
motion again, which allows us to exclude this effect of re-interaction on the
particle creation process. Then, we describe the evolution of the particle
creation with frequencies above $\omega_0$ only as a function of the
relativistic aspect of the mirror's velocity. In other words, we analyze the
formation of relativistic bands in a discrete spectrum of created particles.

Quantum field theory shows that from the perspective of a linearly accelerated observer, an inertial empty space may be full of thermal particles.
Here, we examine the OAM spectrum in a rotating accelerated reference frame to see how the spectrum differs from the linear accelerated case.
To understand how a rotating accelerated observer actually perceives these particles, the Unruh-DeWitt detector and its detailed balance are studied.

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.

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.

We consider the cooperative spontaneous emission of a system of two identical atoms, interacting with the electromagnetic field in the vacuum state.
Using time-dependent theory, we investigate the spectrum of the radiation emitted by the two-atom system.
We show that it is modulated in time, and that the presence of the oscillating mirror can enhance or inhibit the decay rate.

We suggest the measurement of the twist of a chiral mechanical element induced by a gravitational wave.
The induced twist rotates a flat optical mirror on top of this chiral element, leading to the deflection of an incident laser beam.
We estimate a gravitational wave strain sensitivity between 10-21/sqrtHz and 10-23/sqrtHz at around 10 kHz frequency.

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.

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.
