“…The proposed interaction strength is much larger than effects obtainable in single-mode systems, which require the ultrastrong coupling regime (g ≈ ω c ) to have comparable rates [10][11][12]19]. Differently from strain-based methods [5][6][7][8], the proposed mechanism is not limited to a specific choice of emitters and material systems, and it could even be applied to atoms trapped near a mechanical resonator [31][32][33]. Moreover, it provides strong quantum nonlinearities without requiring the single-photon strong optomechanical coupling regime (g 0 ≫ κ).…”

Coherent Atom-Phonon Interaction through Mode Field Coupling in Hybrid Optomechanical Systems

We propose a novel type of optomechanical coupling which enables a tripartite interaction between a quantum emitter, an optical mode and a macroscopic mechanical oscillator. The interaction uses a mechanism we term mode field coupling: mechanical displacement modifies the spatial distribution of the optical mode field, which in turn modulates the atom-photon coupling rate. In properly designed multimode optomechanical systems, we can achieve situations in which mode field coupling is the only possible interaction pathway for the system. This enables, for example, swapping of a single excitation between emitter and phonon, creation of nonclassical states of motion and mechanical ground-state cooling in the bad-cavity regime. Importantly, the emitter-phonon coupling rate can be enhanced through an optical drive field, allowing active control of strong atom-phonon coupling for realistic experimental parameters.

“…First, a phonon can directly couple to a solidstate QE through mechanical strain [5][6][7][8]. Large coupling rates can be obtained in specific systems, but this effect is difficult to engineer and to dynamically control.…”
