Stimulated cooling in non-equilibrium Bose-Einstein condensate
Ka Kit Kelvin Ho, Vladislav Yu. Shishkov, Mohammad Amini +10
We report on the experimental observation of stimulated cooling in the non-equilibrium Bose-Einstein condensate (BEC) of weakly interacting exciton-polaritons from approximately ro…
Kibble-Zurek mechanism in a polariton supersolid
Dmitry Solnyshkov, Rafal Mirek, Darius Urbonas +12
We study the formation of topological defects via the Kibble-Zurek mechanism in a polariton supersolid in a liquid crystal microcavity with tunable Rashba-Dresselhaus spin-orbit co…
Purcell-enhanced single-photon generation from CsPbBr quantum dots in in-situ selected Laguerre-Gaussian modes
Virginia Oddi, Darius Urbonas, Etsuki Kobiyama +9
Single photons in Laguerre-Gaussian (LG) beams, which carry orbital angular momentum (OAM), could enable more robust and efficient photonic quantum communication and information pr…
Entangled Polariton States in the Visible and Mid-Infrared Spectral Ranges
Vladislav Yu. Shishkov, Oleg Kotov, Emily Haughton +5
Entanglement generation in polariton systems is fundamentally constrained by high losses and decoherence, which typically outweigh polariton nonlinearities. Here, we propose a conc…
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
Etsuki Kobiyama, Darius Urbonas, Maryna I. Bodnarchuk +7
Highly ordered nanocrystal (NC) assemblies, namely superlattices (SLs), have been investigated as novel building blocks of optical and optoelectronic devices due to their unique pr…
In-situ tunable, room-temperature polariton condensation in individual states of a 1D topological lattice
Ioannis Georgakilas, Rafał Mirek, Darius Urbonas +4
In recent years, exciton-polariton microcavity arrays have emerged as a promising semiconductor-based platform for analogue simulations of model Hamiltonians and topological effect…
Integrated, ultrafast all-optical polariton transistors with sub-wavelength grating microcavities
Pietro Tassan, Darius Urbonas, Bartos Chmielak +7
All-optical logic has the potential to overcome the operation speed barrier that has persisted in electronic circuits for two decades. However, the development of scalable architec…
All-optical cascadable universal logic gate with sub-picosecond operation
