摘要/Abstract

摘要： The response of a two-electron quantum ring system to the short laser pulses of different shapes in the presence of external static electric field is studied. The variation of transition probabilities of the two-electron quantum ring from ground state to excited states with a number of parameters is shown and explained. The energy levels and wavefunctions of the system in the presence of static electric field are found by solving the time-independent Schrödinger equation numerically by the finite difference method. The shape of the pulse plays a dominant role on the dynamics.
