Dynamical Casimir-Polder effect with Rydberg atoms

Roberto Passante, Roberto Passante

We investigate the dynamics of Rydberg atoms trapped in front of an oscillating conducting mirror, that can be simulated by a wall with a periodically driven dielectric constant (dynamical mirror). We focus our attention on the probability of atomic excitation due to a dynamical Casimir-Polder effect, related to the near field of the image atom whose distance periodically changes as a consequence of the mirror's motion. The theoretical analysis of this system also aims to an experimental proposal to detect this new dynamical effect exploiting Rydberg atoms trapped in the vicinity of the dynamical mirror. Our results indicate that the number of excited atoms is high enough to allow detection of the dynamical effect.

Phase-conjugated mirror-induced oscillations outside the rotating-wave approximation

Saad S. M. Hassan, O. M. Frege

Dynamical behaviour of a single harmonic oscillator (HO) and of a single and two cooperative atoms in front of a phase-conjugated mirror is investigated without using the rotating-wave approximation. The mean photon number of the HO shows transient oscillation of frequency (2?0) and O(?/?0), the ratio of the free-space decay rate to the oscillation frequency, and the fluorescent spectrum becomes asymmetric due to additional resonant and non-resonant dispersive terms. In the single-two-level-atom case, the mean atomic inversion and the fluorescent intensity show steady oscillation O(?0/?0), the ratio of the A-coefficient to the atomic transition frequency. The amplitude of this steady oscillation at frequency (2?0) is larger in the case of two cooperative atoms.
