The spin dynamics is one of the most intriguing research areas of the mesoscopic physics. Investigations in this field are stimulated by the possibility of creation of nanodevices where the spins of single particles become objects of precise manipulation and control. Such nanodevices can be divided into two classes. In spintronic devices one controls the spins of charge carriers (electrons or holes) during the processes of quantum transport. In contrast, in spinoptronic devices the spins of electrically neutral excitons or exciton polaritons in quantum wells and microcavities are controlled. As the exciton spin is directly linked with the polarization of the emitted light, the control of the former brings the possibility to manipulate the latter. The concept of spinoptronic devices has been proposed recently in the works of the applicant . The first element of this type, the polarization controlled optical gate has been very recently realized experimentally . In 2010, we proposed the concept of a hybrid Bose-Fermi system, containing spatially separated but interacting electrons and excitons, where a number of remarkable collective effects are expected, including non-conventional superconductivity.

In the present project we performed theoretical research on the spin dynamics of electrons, holes, excitons, and cavity polaritons in different types of mesoscopic structures. The project was divided into “spinoptronics”, “spintronics” and “hybrid systems” parts. Although the nature of elementary excitations considered in these parts is different, the theoretical description of their spin dynamics can be performed along the similar lines, and many phenomena are analogical in these two types of the systems.

In the course of the project 23 papers related to its topic were published by the members of the consortium. The obtained results can be of use for the design of novel nanoelectronic and optoelectronic components.
