Group of
Quantum Polaritonics
Principal investigator
Alexey Kavokin
Team members
The group is an international leader in the theory of exciton-light coupling in low-dimensional semiconductor structures. It is currently at the heart of a multinational research effort for the realisation of quantum simulators based on the lattices of exciton-polariton condensates and exciton-mediated high-Tc superconductivity
Polaritonics deals with quasi-particles that bind light and matter into new eigenmodes combining antagonist properties such as high coherence inherited from light and strong interactions from their matter counterpart. Polaritons appear ideal for quantum information processing, where both of these features are highly sought. Polariton physics gave a new and applied dimension to fundamental concepts such as Bose-Einstein condensates or superfluids, also bringing them on-chip and up to room temperature. It develops quickly for classical optical devices, with polariton transistors already demonstrated, and the research into polariton simulators is very active, including from our group.
Founded in 2014, and since then the group collaborates with virtually all leading groups studying exciton-polaritons in Russia, EU, USA and Asia, and is highly solicited in international consortia dealing with the field of Polaritonics. The experimental component (since 2017) includes the fabrication and characterisation of novel nano- and meta-materials with tailored optical and transport properties. More than 50 publications from the group is affiliated to the RQC since 2014, including prestigious Nature Materials, Nature Communications, Light: Science and Applications, Physical Review Letters, and the "Microcavities" textbook (Oxford University Press, 2017, 600 pages).
