Title: Interference phenomena in the asymmetric dynamical Casimir effect for a single $\delta-\delta^{\prime}$ mirror

Abstract summary: 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.

Abstract: The interaction between the quantum vacuum and time-dependent boundaries can produce particles via the dynamical Casimir effect. It is known that, for asymmetric Casimir systems, there is an imbalance in the particle production on either side of the boundary. Here, we consider a real massless scalar field in 1+1 dimensions interacting with a moving $\delta-\delta^{\prime}$ mirror with time-dependent properties. The spectral distribution and particle creation rate are computed, which now include an additional interference term that can affect different parts of the spectrum in a constructive or destructive manner. The asymmetry of the system is investigated by analyzing the difference in particle spectra produced on the two sides of the mirror. Additionally, we also explore enhancement of the spectrum and its asymmetry within the context of a stationary $\delta-\delta^{\prime}$ mirror subject to multiple fluctuation sources.

Entangled multiplets, asymmetry, and quantum Mpemba effect in dissipative systems [0.0]
We conjecture a quasiparticle picture for the charged moments of the reduced density matrix, which are the main ingredients to construct the asymmetry. By using the Lindblad master equation, we study the effect of gain and loss dissipation on the entanglement asymmetry.

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.

Effect of a moving mirror on the free fall of a quantum particle in a homogeneous gravitational field [0.0]
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.

Exploring symmetries in photoelectron holography with two-color linearly polarized fields [0.0]
We investigate photoelectron holography in bichromatic linearly polarized fields of commensurate $romega$ and $somega$. We show that, additionally to the well-known half-cycle symmetry, which is broken for $r+s$ odd, there are reflection symmetries around the field zero crossings and maxima. We analyze how these features affect the ionization times and saddle-point equations for different bichromatic fields.

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.

Quantum asymmetry and noisy multi-mode interferometry [55.41644538483948]
Quantum asymmetry is a physical resource which coincides with the amount of coherence between the eigenspaces of a generator. We show that the asymmetry may emphincrease as a result of a emphdecrease of coherence inside a degenerate subspace.

Collective spontaneous emission of two entangled atoms near an oscillating mirror [50.591267188664666]
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.

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.
