Towards the light-phonon quantum interface with an atomic array in a cavity — •Oxana Mishina and Giovanna Morigi — Saarland University, Saarbruecken 66123, Germany

This work explores theoretically the accessibility of the multimode quantum interface, involving the modes of collective motion on the atomic array and a single mode optical cavity. This system is similar to thous experimentally implemented in the works [1,2]. The controlability of the array motion is theoretically demonstrated by cooling all the atoms to the ground state of the individual traps with experimentally feasible conditions. Together with the theoretical model developed in this work it sets the basis for the further exploration of the quantum optomechanical interface and, possibly, generation of novel non-classical states of collective atomic motion.
