Phys. Rev. Lett. 100, 046805 (2008) [4 pages]Optical Control in Coupled Two-Electron Quantum DotsReceived 14 August 2007; published 1 February 2008 The dynamics of two electrons in a 2-dimensional quantum dot molecule in the presence of a time-dependent electromagnetic field is calculated from first principles. We show that carefully selected microwave pulses can exclusively populate a single state of the first excitation band and that the transition time can be further decreased by optimal pulse control. Finally we demonstrate that an oscillating charge localized state may be created by multiple transitions using a sequence of pulses. © 2008 The American Physical Society URL:
