Topological quantum systems and materials

1. Physical properties of topological phases, characterization of topological phases and topological phase transitions

2. Geometric topology and topological phases in shape deformed nanostructures (semiconductors and superconductors)

3. Topological phases in superconductor-semiconductor nanostructures

4. Manipulating topological states in hybrids based on chiral and helical topological superconductors

5. Adiabatic quantum computation in the presence of a phonon decoherence bath

We use light to fabricate and characterize integrated quantum photonic components. In particular, we use femtosecond laser pulses to produce photonic circuits in transparent materials, as glasses and crystals, for quantum applications. Recent work focussed on the development of photonic circuits in glass for the manipulation of single photons, in crystal for the demonstration of quantum memories and in diamond for a photonic interface with color-center defects. We use ultrafast laser pulses for the characterization of single photon sources based on 2D materials.

The group studies Bose-Einstein condensates of excitons and exciton-polaritons in various crystal structures. We are particularly interested in application of bosonic condensates for realisation of the exciton-mediated superconductivity. Our research paves way to realisation of quantum simulators based on the gratings of trapped exciton-polariton condensates linked by Josephson and radiative coupling. Some of materials we study allow for the room temperature function (in particular, ZnO, transition metal dichalcogenides).
