Abstract in another language
A theoretical analysis of the optically driven spin dynamics of a single Mn atom in a quantum dot in the presence of magnetic fields in different geometries is presented. When a magnetic field in Faraday configuration is applied, the Mn spin can be flipped from its initial state into each of its six spin eigenstates via optical excitation and manipulation of excitons. In the case of a magnetic field in Voigt configuration, the presence of an exciton leads to a precession of the Mn spin around the combination of external and exchange-induced magnetic field. By using optical pulses this precession can be switched on and off.
