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…
Dynamic topological exciton-polaritons enabling ultrafast logic operations
Feng Jin, Hao Zheng, Zhe Zhang +7
Topological active materials have emerged as powerful paradigm bridging the discovery of exotic topological phases of matter with the development of functional topological devices.…
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…
Trembling Motion of Exciton-Polaritons Close to the Rashba-Dresselhaus Regime
Wen Wen, Jie Liang, Huawen Xu +4
We report the experimental emulation of trembling quantum motion, or Zitterbewegung, of exciton polaritons in a perovskite microcavity at room temperature. By introducing liquid cr…
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…
Perovskite topological exciton-polariton disclination laser at room temperature
Feng Jin, Subhaskar Mandal, Xutong Wang +2
Topologically nontrivial systems can be protected by band topology in momentum space, as seen in topological insulators and semimetals, or real-space topology, such as in lattice d…
