Abstract

The phonon-induced dephasing dynamics in optically excited semiconductor quantum dots was studied. The study was conducted within the frameworks of the independent boson model and optimal control. The dot states in terms of a generic two-level system, with ground state 0 and excited state x were described. The results show that appropriate tailoring of laser pulses allow complete control of the optical excitation despite the phonon dephasing.
