Light scattering in an optomechanical cavity coupled to a single atom

Abstract

We theoretically analyze the light scattering of an optomechanical cavity which strongly interacts with a single two-level system and couples simultaneously to a mechanical oscillator by radiation forces. The analysis is based on the assumptions that the system is driven at low intensity, and that the mechanical interaction is sufficiently weak, permitting a perturbative treatment. We find quantum interference in the scattering paths, which allows to suppress the Stokes-component of the scattered light. This effect can be exploited to reduce the motional energy of the mechanical oscillator.

Electromagnetically-induced-transparency control of single-atom motion in an optical cavity

“…These techniques can be extended for cooling optomechanical systems [37] coupled to a single emitter [38]. Our setup, moreover, can serve as a transducer between the vibrational, electronic and photonic degrees of freedom, thereby realizing a continuous-variable quantum interface with single atoms [39].…”

Suppression of Rabi oscillations in hybrid optomechanical systems

“…An obvious extension of the paradigmatic optomechanical system, i.e an optical cavity coupled to a mechanical element by radiation forces whose motion changes the cavity's boundaries, can be achieved by adding a single two-level system which couples to the cavity light field by dipole interaction, thereby combining cavity optomechanics with cavity quantum electrodynamics. Besides conventional quantum electrodynamics experiments with macroscopic cavities investigations of such systems are of particular importance for solid-state systems, such as two-level systems in optomechanical crystals [5][6][7]. In circuit electromechanical setups the coupling to two-level systems has already been demonstrated [8][9][10][11].…”

Single-photon transport in a one-dimensional waveguide coupling to a hybrid atom-optomechanical system

“…This kind of hybrid atom-optomechanical system consists of an optomechanical cavity interacting with a single two-level atom, and is suggested to achieve a strong coupling between a single trapped atom and the motion of a membrane [30]. Notably, a weak continuous-wave laser scattering problem in this hybrid atom-optomechanical system was perturbatively treated in a recent study by assuming the weak coupling, [31]. Here, we employ a full quantum-mechanical approach [1,2,29] to study the transmission and reflection properties of the propagating photon in the waveguide in the strong optomechanical coupling regime.…”
