Highly detuned Rabi oscillations for a quantum dot in a microcavity

Pronounced Rabi oscillations at large detunings are predicted for a system consisting of a semiconductor quantum dot in a microcavity. Besides an anticrossing at zero detuning, two additional anticrossings are possible at microcavity detunings of one longitudinal-optical-phonon frequency below and above the quantum-dot resonance. These phonon-assisted Rabi oscillations generally exhibit complex spectral features. The investigation is performed with a quantum-electrodynamical model, where the phonon reservoir effects are treated beyond the customary Markov, second-order Born approximation. © 2013 American Physical Society.
