A model study on multiple optically driven emitters coupled to a common phononic environment — •Daniel Groll1, Daniel Wigger2, and Tilmann Kuhn1 — 1Institute of Solid State Theory, University of Münster, Germany — 2Department of Physics, University of Münster, Germany
Single photon emitters in a solid state environment are inevitably coupled to the phonon modes of the host material. While this interaction channel is often seen as a drawback, leading to decoherence, it also allows for control of emitters via phonons in the context of hybrid quantum systems. Here we investigate the optically induced dynamics of multiple emitters interacting with a common phononic environment and show that such a coupling leads to an effective interaction between the spatially separated emitters.
In the case of emitters coupling strongly to a single phonon mode, e.g., realized by multiple quantum dots embedded in a surface acoustic wave resonator, we predict distinct deviations from the Mollow triplet spectrum in resonance fluorescence under strong optical driving.
In the case of coupling to an anharmonic phonon bath, leading to pure dephasing in addition to the effective emitter-emitter–coupling, we investigate the complex dynamics of such a driven-dissipative quantum system.
