We develop a theory of phonon-induced photoluminescence from a quantum dot in the regime of vibrational resonance. Using the generalized model for renormalization of the quantum dot's energy spectrum and the density matrix formalism, we derive an expression for the differential cross-section of the phonon-induced photoluminescence from a quantum dot.
We developed the theory of time-resolved secondary emission from semiconductor nanodumbbells. We reveal conditions that the signal of secondary emission is described by a simple formula regardless of the pulse shape. This formula may prove useful for studying the dephasing and relaxation parameters of the nanodumbbell electronic subsystem.
