Optical And Electronic Properties

Quantum dots semiconductor heterostructures exhibit optical and electronic properties similar to those of real atoms, due to the delta like dispersion of the density of states. The study of the optical and electronic properties of artificial atoms in high magnetic fields allows the observation of quantum effects typical of the atomic physics. In this work we review the problem of artificial atoms in magnetic fields starting from the single-particle theory up to the problems encountered in the observation of correlation effects when two or more carriers are confined in the dot. The main experiments elucidating the change of the optical and electronic properties of artifical atoms in magnetic fields are also reviewed.

Connecting The Dots

The mixed phase space in an open quantum dot array with a soft confining potential is studied in low and high magnetic fields. Chaos occurs due to the perturbations by the constrictions connecting the dots of the array. Regular orbits and the areas of Kalmogorov-Arnold-Moser islands in phase space become increasingly dominating with increasing magnetic field. The correspondence to the high-field quantum-mechanical picture in a 2D electron system with boundaries is discussed.
