Oscillatory impurity potential induced dynamics of doped quantum dots: Analysis based on coupled influence of impurity coordinate and impurity influenced domain
NK Datta, M Ghosh - Chemical Physics, 2010 - Elsevier
We explore the pattern of time evolution of eigenstates of a repulsive impurity doped
quantum dot. The quantum dot is 2-dimensional and contains one electron which is
harmonically confined. We have considered Gaussian impurity centers. A static transverse
magnetic field is also present. Under a periodically fluctuating impurity potential, the system
reveals a long time dynamics that is undulatory in nature. Coupled to the dopant location,
the domain of influence of the impurity potential affects the separation between the …
