Dynamical Casimir effect for a swinging cavity

Abstract

The resonant scalar particle generation for a swinging cavity resonator in the Casimir vacuum is examined. It is shown that the number of particles grows exponentially when the cavity rotates at some specific external frequency.

Fifty Years of the Dynamical Casimir Effect

“…The case of the TE polarization of the vector EM field was also considered there. The "swinging" cubic cavity, performing small amplitude periodical rotations along the z-axis, θ(t) = sin(Ωt), was considered in [284] (in the model of scalar field). The frequency Ω was chosen in such a way that three modes, (1, 1, 1), (1, 2, 1) and (2, 1, 1), were resonantly coupled.…”

Mode-mixing quantum gates and entanglement without particle creation in periodically accelerated cavities

“…The particle creation resonance (8b) is well known in the DCE literature [3,4,7,10,[19][20][21][22][23][24][25][26][27]. The mode-mixing resonance (8a) has been noted [10,[19][20][21][22][23][24] but seems to have received attention mainly in situations where it happens to coincide with a particle creation resonance. As the case of interest in the experimental scenario of section 4 will be mode mixing without significant particle creation, we recall here some relevant properties of mode mixing in quantum optics.…”

Entanglement generation in relativistic cavity motion

“…where in each case m − n needs to be odd in order for the coefficient to be nonvanishing. The particle creation resonance ( 7) is well known in the DCE literature [3,4,28,29,30,31,32,33,34,35,36,37,38]. The mode mixing resonance ( 6) is also known [29,30,31,32,33,34,35] but seems to have received significant attention only in situations where it happens to coincide with a particle creation resonance.…”
