报告题目： Numerical modeling of strong coupling between quantum emitter and nanocavities
Optical cavities alter the electromagnetic field that quantum emitter experiences, thus being widely utilized in light-matter interaction. Past decades have seen enormous progresses of cavity-enhanced radiation, which refers to the weak coupling regime. In the strong coupling regime, the cavity and the emitter form a hybridized system with mixed states, and exchange energy coherently. Such strong coupling system constitutes the fundamental building blocks for quantum information processing. Although single-emitter strong coupling had been realized with dielectric microcavities several years ago, cryogenic temperature condition and complex experimental setup restricted its practical applications .
Recently, plasmonic cavities with ultrasmall mode volume have enabled single-emitter strong coupling at room temperature. With these inspiring experimental achievements, a numerical platform to model strong coupling systems is demanded. In this talk, we will discuss our Finite-Difference Time-Domain (FDTD) numerical modeling of strong coupling between J-aggregate and sphere dimer, and provide guidelines for experimental implementation. Equipped with such numerical platform, we are able to explore more fancy nanostructures or mechanisms that ease the applications of strong coupling.
