Effective potential engineering by emergent anisotropy in a tunable open-access microcavity
Yiming Li, Xiaoxuan Luo, Yaxin Guo +11
Photonic spin-orbit (SO) coupling is an important physical mechanism leading to numerous interesting phenomena in the systems of microcavity photons and exciton-polaritons. We repo…
Experimental measurement of the divergent quantum metric of an exceptional point
Qing Liao, Charly Leblanc, Jiahuan Ren +6
The geometry of Hamiltonian's eigenstates is encoded in the quantum geometric tensor (QGT). It contains both the Berry curvature, central to the description of topological matter a…
Spin-orbit coupling in photonic graphene
Zhaoyang Zhang, Shun Liang, Feng Li +6
We generate experimentally a honeycomb refractive index pattern in an atomic vapor cell using electromagnetically-induced transparency. We study experimentally and theoretically th…
Nontrivial band geometry in an optically active system
Jiahuan Ren, Qing Liao, Feng Li +6
Optical activity (OA), also called circular birefringence, is known for two hundred years, but its applications for topological photonics remain unexplored. Unlike the Faraday effe…
