Motion induced by asymmetric excitation of the quantum vacuum

Dynamical Casimir effect enhanced by decreasing the mirror reflectivity

“…Moreover, the vertical line given by χ 0 = 0 corresponds to the normalized particle creation rate for the model used in Ref. [18], when the oscillatory behavior given in Eq. ( 33) is considered.…”

“…It was adopted by Moore [1], De-Witt [2], Fulling and Davies [3], and also in many other works as, for instance, in Refs. [14][15][16][17][18]. In (1 + 1)D, the simulation of a motionless mirror with internal properties varying in time was proposed by Silva and Farina [15], who considered the quantum vacuum field submitted to a time-dependent Robin boundary condition on a static mirror.…”

“…The use of δ − δ ′ potentials (δ ′ is the derivative of the Dirac δ) has also been considered as, for example, in Refs. [17,18,29,30]. In the limit of a perfectly reflecting mirror, the δ − δ ′ model leads to a situation where the field obeys the Robin boundary condition on one side, and the Dirichlet condition on the other side of the mirror [17].…”

First- and Second-Order Forces in the Asymmetric Dynamical Casimir Effect for a Single δ − δ′ Mirror

“…This phenomenon has been thoroughly investigated for numerous theoretical configurations (see [1][2][3] for several detailed reviews of this topic) and has also been experimentally verified [4]. There has been recent interest in understanding the consequences of modifying DCE systems by introducing asymmetric boundary conditions to a mirror undergoing time-dependent interactions with the quantum vacuum [5][6][7][8][9]. This asymmetry leads to an asymmetric spectrum of produced particles in what is now known as the asymmetric dynamical Casimir effect (ADCE).…”

“…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.…”
