Beam canalization by a non-Abelian gauge field

Olha Bahrova, Jiahao Ren, Feng Jin +3

Hyperbolic and quasi-flat isofrequency contours (IFCs) are used for beam canalization and can be created by tilted Dirac points in photonic systems. Dirac points in microcavities a…

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…

Electrically-injected room-temperature waveguide polariton laser

Hassen Souissi, Valentin Develay, Maksym Gromovyi +14

Exciton-polariton lasers are coherent light sources which do not require the population inversion (transparency) condition to be fulfilled. They have been conceptualized at the end…

Annihilation of Dirac points and its topological obstruction in a photonic Kagome lattice

Zhaoyang Zhang, Matthieu Finck, Changchang Li +7

Dirac points (DPs) are topological singularities that determine the extraordinary properties of two-dimensional materials. They are generally classified by discrete topological inv…

Optically reconfigurable canalization of exciton-polaritons in a non-hyperbolic perovskite

Jiahao Ren, Olha Bahrova, Feng Jin +5

The ability to steer polariton flow on-demand holds significant promise towards nanophotonic applications and photonic circuitry. Polariton canalization, exhibiting intrinsic colli…

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…
