Abstract in another language
The ultrafast light-induced dynamics in an InAs quantum dot doped with a single Mn atom is studied theoretically. Due to the exchange interaction between the Mn atom and the acceptor hole in the quantum dot, an effective two-level system is formed in the ground-state manifold. We show that this two-level system can be controlled coherently on a picosecond time scale. The control involves an optical manipulation of the quantum dot exciton by using either a series of two ultrafast pulses or a single extended laser pulse. For the excitation with two pulses, we discuss the optical signals that could be used in time-resolved spectroscopy to monitor the dynamics. We compare these results to the spin dynamics in a CdTe quantum dot doped with a single Mn atom.
