Electrically reconfigurable extended lasing state in an organic liquid-crystal microcavity
Dmitriy Dovzhenko, Luciano Siliano Ricco, Krzysztof Sawicki +12
Small-footprint, low-power arrays of coupled coherent emitters with the capability of near- and far-field engineering and coherence control are highly sought after to meet modern n…
Spin-to-orbital angular momentum conversion in non-Hermitian photonic graphene
Zhaoyang Zhang, Pavel Kokhanchik, Zhenzhi Liu +7
Optical beams with orbital angular momentum (OAM) have numerous potential applications, but the means used for their generation often lack crucial on-demand control. In this work,…
Beam dynamics induced by the quantum metric of exceptional rings
Zhaoyang Zhang, Ismaël Septembre, Zhenzhi Liu +10
Topological physics has broadened its scope from the study of topological insulating phases to include nodal phases containing band structure singularities. The geometry of the cor…
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…
Electrically tunable spin-orbit coupled photonic lattice in a liquid crystal microcavity
Marcin Muszyński, Przemysław Oliwa, Pavel Kokhanchik +12
We create a one-dimensional photonic crystal with strong polarization dependence and tunable by an applied electric field. We accomplish this in a planar microcavity by embedding a…
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…
Non-Hermitian skin effect induced by Rashba-Dresselhaus spin-orbit coupling
Pavel Kokhanchik, Dmitry Solnyshkov, Guillaume Malpuech
1D chains with non-reciprocal tunneling realizing the non-Hermitian skin effect (NHSE) have attracted considerable interest in the last years whereas their experimental realization…
Control of dimer chain topology by Rashba-Dresselhaus spin-orbit coupling
Pavel Kokhanchik, Dmitry Solnyshkov, Thilo Stöferle +3
We study theoretically a dimer chain in the presence of Rashba-Dresselhaus spin-orbit coupling (RDSOC) with equal strength. We show that the RDSOC can be described as a synthetic g…
Photonic Berry curvature in double liquid crystal microcavities with broken inversion symmetry
Pavel Kokhanchik, Helgi Sigurdsson, Barbara Piętka +2
We investigate a photonic device consisting of two coupled optical cavities possessing Rashba-Dresselhaus spin-orbit coupling, TE-TM splitting, and linear polarisation splitting th…
