“…To better understand the ADCE, it is convenient to investigate the interaction between the quantum vacuum and a partially transparent mirror in a (1 + 1)D (dimensional) spacetime. This is achieved by modeling the mirror as δ − δ ′ potential [5,6,[10][11][12][13][14][15][16] (δ ′ being the spatial derivative of the Dirac δ function). Previous literature has explored the ADCE spectrum of a moving δ − δ ′ mirror [5] and a δ − δ ′ mirror with time-dependent material properties [6] as well as when the mirror possesses both of these independent fluctuation sources.…”

Here, we consider an asymmetric δ−δ′ mirror undergoing time-dependent interactions with a massless scalar field in 1 + 1 dimensions. Using fluctuation-dissipation theory for a mirror in vacuum, we compute the force on a moving δ−δ′ mirror with time-dependent material properties. We investigate the first-order forces arising from the two distinct fluctuation sources and calculate the linear susceptibility in each case. We then plot the resulting forces. At the second order, we also find the independent contributions to the total force as well as the force that arises from the interference phenomena between the two fluctuation sources.

A mirror with time-dependent boundary conditions will interact with the quantum vacuum to produce real particles via a phenomenon called the dynamical Casimir effect (DCE). When asymmetric boundary conditions are imposed on the fluctuating mirror, the DCE produces an asymmetric spectrum of particles. We call this the asymmetric dynamical Casimir effect (ADCE). Here, we investigate the necessary conditions and general structure of the ADCE through both a waves-based and a particles-based perspective. We review the current state of the ADCE literature and expand upon previous studies to generate new asymmetric solutions. The physical consequences of the ADCE are examined, as the imbalance of particles produced must be balanced with the subsequent motion of the mirror. The transfer of momentum from the vacuum to macroscopic objects is discussed.
