Spin related phenomena in mesoscopic transport

The spin dynamics is one of the most intriguing research areas within 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, i.e. spintronic devices. Another important topic in the field of mesoscopic transport is connected with many- body correlations, which manifest itself via variety of intriguing physical phenomena. In many of them spin plays a major role. The analysis of the interplay between spin dynamics and mesoscopic manybody correlations is thus an actual task. In a current Multidisciplinary Marie Curie FP7-PEOPLE-IRSES project SPINMET we were analyzing many body spin related phenomena in various types of mesoscopic structures focusing on following main topics: i) Spin- interference phenomena in non-single connected mesoscopic objects ii) "0.7 anomaly" and related phenomena in 1D ballistic transport iii) New states of quantum spinor 1D liquids. iv) Spin transport in quantum microcavities The final objective is to understand the mechanisms controlling mesoscopic spin dynamics and its interplay with many-body correlations and to formulate the practical recommendations for their applications in High-Tech industry specifically as the silicon spin transistor without ferromagnetic contacts, the resistance standard based on the quantum spin Hall effect, the compact source of the THz irradiation etc. To achieve the goals we created the distributed consortium (network) of partner institutions consisting of both experimental and theoretical teams located in EU and associated countries (Iceland, UK, Switzerland) and in Eligible Third Countries (Russia, Brazil). Each of them has its own specialization and related with others by virtue of already existing collaborative links. In course of the project we suppose to amplify and order these collaborations and create the new links between partners under central common idea of studying fundamental aspects of mesoscopic dynamics and its practical applications. The current IRSES project appears to promote further development of high mobility self-assembled silicon quantum well technology that is performed by the Petersburg teams as well as effective application of the nanostructures prepared in both fundamental physics of spin-dependent processes and the experimental realization of quantum computing elements. The interplay of theoretical and experimental groups involved in the project brings forward new results in nano-scale physics that are suggested to be used in educational courses in partner organisations. The IRSES project promotes the enhancement of scientific level of MD and PhD students involved in the project, specifically to be familiar with last trends in a field of mesoscopic spin transport.
