ABSTRACT: We analyze the spontaneous emission dynamics of a V-type quantum emitter close to a molybdenum disulfide (MoS2) nanodisk. We show that a MoS2 nanodisk leads to both high-degree quantum interference and non-Markovian dynamics in the spontaneous emission of the nearby quantum emitter. We analyze the spontaneous emission dynamics by combining quantum dynamics calculations with electromagnetic calculations. A rich population dynamics ranging from decaying Rabi oscillations to complex decaying oscillations and strong population exchange between the upper states of the quantum emitter is obtained depending on the parameters of the system. Our results have potential applications in quantum technologies.

[21] In case of a disk with radius R = 7.5 nm, the fitting procedure results in β = 5.811 · 10−4 ± 7.08 · 10−5 eV for ωc = 1.956 eV. We note that these values in both cases are obtained by applying a single peak fitting to J˜±(ω) using J L(ω) at the above ωc values.
