Quantum effects and low-dimensional systems

Квантовые явления и низкоразмерные системы
In modern nanoelectronic devices, such as atomic force microscope, superfine capacitors, microcavities the laws of classical electrodinamics are superseed by quantum electrodynamics laws. The atoms are subjected to different forces including the quantum fluctuations of the matter fields as well as quantum fluctuation of surrounding electromagnetic field. All theoretical problems of finite volume quantum electrodynamics are of practical interest for thin film electronics and nanomechanics. The arrays of metall and semiconductor quantum dots on heterostructures are of special interest as a new class of metamaterials. Quantum dots are the analogs of large artificial atoms. The system of quantum dots can be considered as giant molecules with externally controlled parameters. For instance tuning the strength of the external magnetic field one can control the energy gap between the triplet and the singlet electronic states of quantum dots. The energy spectra, dispersion laws, wave function localization, electron and exciton transport are studied both analytically and numerically. In contrast to ordinary atoms the energy spectra of quantum dots and their systems are rather sensitive to moderate values of laboratory magnetic fields. Therefore the fine control of the features of quantum dots, QD molecules and arrays is perspective for opto and nanoelectronics.
