Interfacing Optomechanics with Rydberg Atoms — •Adrian Sanz Mora, Alexander Eisfeld, Sebastian Wüster, and Jan-Michael Rost — Max Planck Institute for the Physics of Complex Systems, Dresden

We investigate the mutual coupling of a three-level ultracold gas and a micro mechanical oscillator via electromagnetic radiation. The atoms interact with the probe- and control beams that electromagnetically induce transparency (EIT) [1] in the gas.

Both of these couple to the mechanical motion of a vibrating mirror via radiation pressure forces. The power of the probe light field is modulated by the absorption of the atoms, providing coupling of the gas to the mirror.

The control light field is phase-modulated by mirror vibrations, providing coupling of the mirror to the gas. For classical light fields and simplified response of the gas, we explore damping or driving of the mirror. By assuming that the third level is a Rydberg state, our setup can interface optomechanics [2] with Rydberg physics.
