Outline of Final Research Achievements

We have developed a computational system for simulating dynamics of light-coupled artificial atoms for future applications to nano-optical devices. Maxwell's equations and the time-dependent Schroedinger equation that are responsible respectively for the propagation of the electromagnetic field and of the electrons have been solved relying on the finite difference time domain method and on the symplectic integrator method, respectively. The developed computational system has been applied to investigate the dynamics of electrons in artificial atoms subjected to incident laser pulses.
