Many-body dynamics of the decay of excitons of different charges in a quantum dot
We calculate the photoluminescence spectrum of a single semiconductor quantum dot
strongly coupled to a continuum as a function of light frequency, gate voltage, and magnetic
field. The spectrum is dominated by the recombination of several excitonic states which can
be considered as quantum quenches in which the many-body nature of the system is
suddenly changed between initial and final states. This is associated with an Anderson
orthogonality catastrophe with a power-law singularity at the threshold. We explain the main …
