Scope

In recent years condensed matter physics has broadened its scope beyond its traditional boundaries. Nowhere is this broadening more apparent than in investigations of nanometer-scale systems, where the effects of the dimensional quantization play a major role. Mesoscopic physics became a field of the intense research in last two decades. A number of the new intriguing phenomena was observed in this domain, namely the quantum Hall effect, the conductance quantization in the quantum wires and quantum point contacts, strong coupling between the exciton and photon modes in quantum microcavities and others. Many of these effects are of great interest from the fundamental point of view. Besides, various mesoscopic objects can serve as components of the electronic and optoelectronic devices of the new generation, such as one-electron transistors, spin transistors and spin filters, polariton lasers etc. The problem of the spin dynamics is one of the most interesting in mesoscopic physics. The investigations in this field are stimulated by the possibility of creation of nano-devices where the spin of the single particles could be an object of the precise manipulation and control. The interplay between the spin-dynamics and many-body interactions is of special interest, as it was shown to be of crucial importance in the variety of the intriguing phenomena such as metal- dielectric transition in low- dimensional systems and anomalies of the conductance of the quantum wires and ballistic rings. The main motivation for the upcoming workshop is the apparent need to encourage interaction and information exchange between researchers working in the field of spin-related phenomena in various mesoscopic systems, as well as between experimentalists and theoreticians. Therefore, from the broad range of experienced researchers working in these new areas, we plan to invite outstanding researchers in order to allow them to share their experience during the program with the younger participants. From the broad list of spin-dependent phenomena in mesoscopic system we plan to make a special accent on following topics
  • Spin interference in nano- scale objects and spin devices
  • Kondo- related phenomena in mesoscopic systems
  • “0.7 anomaly” and related nonequilibrium phenomena in the ballistic conductance of quantum wires and quantum point contacts
  • Spin transport of excitons and cavity polaritons
  • Localization and manipulation of spin and charge
  • The multidisciplinary nature of the proposed workshop will allow to familiarize the participants with different subjects, to encourage inter-domain collaboration, and to share experience of different research fields with one another. In this way, we intend to stimulate new and fruitful cooperation across subject frontiers as well as between experimental and theoretical groups.

    Timetable

    Format

    The program of the overall duration of 4 weeks would contain two parts: “spintronic” part (spin transport of the electrons and holes) and “spinoptronics” (spin dynamics of excitons and exciton polaritons). The one week focus event is planned between the two parts of the program, which will unite the participants from both of them. Generous time is reserved for discussions/and other interactions. During each working day we plan to organize day one or two oral presentations of the duration of 1-2 hours each. Several participants will give short lecture courses on general subjects related to mesoscopic spin transport. These will include

    1. General aspects of mesoscopic transport
    2. Spin-orbit coupling in mesoscopic systems
    3. Strongly correlated spin systems: theoretical and experimental aspects
    4. Ab-initio modeling of materials for spintronics
    5. Polariton transport
    6. Spin transport of indirect excitons
