Research interests in our research group

We study the quantum and classical phenomena in small electronic systems, with a focus on superconductivity, magnetism, topological media and optomechanics. Our approach is based on phenomenological low-energy theory of quantum systems. In each project we work in close collaboration with world-leading experimental groups.

Present research topics

  • Flat-band superconductivity and magnetism. We study interacting phases in systems with exotic electronic dispersion.
  • Electronic properties of graphite and their relation to topological media. In particular, we seek models to explain high-temperature interface superconductivity observed in graphite. We are also extending such studies to generic artificial topological structures.
  • Nonequilibrium and thermoelectric effects in superconductor-ferromagnetic hybrid structures. Recent studies include characterisation of nonequilibrium modes in this type of systems, and the possible use of such systems as efficient radiation detectors.
  • Magnetization dynamics especially in superconductor/ferromagnet heterostructures. The key problems are the studies of spin torque and its reciprocal effect, spin pumping.
  • Open quantum systems in various disguises. We have especially studied quantum optomechanics, and in particular their microwave realisations, and at present we study the measurement of strongly coupled plasmon-polariton systems with quantum emitters (two-level systems).
