Multiple Quantum Well in static magnetic field and intense laser pulses

• Multiple quantum well in external fields.
• Energy spectrum and dipole matrix elements.
• Short laser pulses.
• Dynamics by solving time-dependent Schrodinger equation.

The energy spectrum and dipole matrix elements of a multiple quantum well (MQW) system has been calculated numerically by solving the time-independent Schrödinger equation using finite difference method, in the presence of magnetic field. The effect of barrier width is also investigated. The energy difference between the levels of various minibands and the energy difference between various levels of the same miniband is calculated for different number of wells in the MQW. Finally, the dynamics of the system in short laser pulses has been calculated numerically by solving the time-dependent Schrödinger equation. The effect of magnetic field on the dynamics is clearly shown and explained.
