Transition between cooperative emission regimes in giant perovskite nanocrystals
Etsuki Kobiyama, Gabriele Rainò, Yuliia Berezovska +6
Interactions between emitters within an ensemble can give rise to cooperative processes that significantly alter the properties of the emitted light. One such process is superfluor…
A framework to compute resonances arising from multiple scattering
Jan David Fischbach, Fridtjof Betz, Nigar Asadova +8
Numerous natural and technological phenomena are governed by resonances. In nanophotonics, resonances often result from the interaction of several optical elements. Controlling the…
Room-temperature cavity exciton-polariton condensation in perovskite quantum dots
Ioannis Georgakilas, David Tiede, Darius Urbonas +13
The exploitation of the strong light-matter coupling regime and exciton-polariton condensates has emerged as a compelling approach to introduce strong interactions and nonlineariti…
In-situ tunneling control in photonic potentials by Rashba-Dresselhaus spin-orbit coupling
Rafał Mirek, Pavel Kokhanchik, Darius Urbonas +15
The tunability of individual coupling amplitudes in photonic lattices is highly desirable for photonic Hamiltonian engineering and for studying topological transitions in situ. In…
Observation of a supersolid phase in a spin-orbit coupled exciton-polariton Bose-Einstein condensate at room temperature
Marcin Muszyński, Pavel Kokhanchik, Rafał Mirek +18
In Bose-Einstein condensates (BEC), spin-orbit coupling (SOC) produces supersolidity. It is a peculiar state of matter, which, in addition to the superfluid behaviour shows periodi…
Perovskite nanocrystal self-assemblies in 3D hollow templates
