Dynamics of 2-D one electron quantum dots in pulsed field: Influence of size Original Research Article

We explore the dynamics of harmonically confined single electron quantum dots as a function of dot size when an external time varying pulsed electric field is switched on. The system of interest is a 2-D system in the presence of a perpendicular magnetic field. We show that for given strengths of the confining potentials, the pattern of time evolution of eigenstates of the unperturbed system reveals significant size-dependence. The pulse duration time is also found to modulate the dynamical aspects in a prominent way.
