The current research activities in the Device Theory group focus on theory of electronic transport in micro- and nano-structures involving superconductors (high Tc and low Tc) and other materials: normal metals, semiconductors and metallic ferromagnets. The application of these structures in novel (quantum)-electronic devices is investigated. This research is divided into several directions:
- Nonequilibrium effects in Josephson junctions: theory of particle detection with superconducting tunnel junctions and nonequilibrium effects in double-barrier junctions (supported by ESA/ESTEC).
- Proximity and Josephson effect in superconductor-ferromagnet (SF and SFS) junctions: theoretical study of current-phase relation and mechanisms of 0-pi transitions in SFS junctions and their arrays (supported by FOM).
- Thermodynamic and transport properties of anisotropic and multiband superconductors and application to the new superconductor MgB2.
- Macroscopic Quantum Tunneling (MQT) in unconventional Josephson junctions involving d-wave superconductors or SFS pi-junctions (supported by NanoNed program).
- General symmetry properties and odd-frequency pairing in spatially inhomogeneous superconductors.
