Helical polariton lasing from topological valleys in an organic crystalline microcavity
Teng Long, Xuekai Ma, Jiahuan Ren +6
Topological photonics provides an important platform for the development of photonic devices with robust disorder-immune light transport and controllable helicity. Mixing photons w…
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…
Quantum metric and wavepackets at exceptional points in non-Hermitian systems
D. D. Solnyshkov, C. Leblanc, L. Bessonart +5
The usual concepts of topological physics, such as the Berry curvature, cannot be applied directly to non-Hermitian systems. We show that another object, the quantum metric, which…
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…
