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…
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…
Observation of polaritonic flat-band bound states in the continuum in a 2D magnet
Fuhuan Shen, Jiahao Ren, Zhiyi Yuan +5
Flat-band bound states in the continuum (BICs) are topological states with suppressed group velocity and robustness against radiation loss, offering a powerful platform for the exp…
Observation of perovskite topological valley exciton-polaritons at room temperature
Feng Jin, Subhaskar Mandal, Zhenhan Zhang +7
Topological exciton-polaritons are a burgeoning class of topological photonic systems distinguished by their hybrid nature as part-light, part-matter quasiparticles. Their further…
