Dual orthogonally-polarized lasing assisted by imaginary Fermi arcs in organic microcavities
Teng Long, Jiahuan Ren, Peng Li +6
The polarization control of micro/nano lasers is an important topic in nanophotonics. Up to now, the simultaneous generation of two distinguishable orthogonally-polarized lasing mo…
Optical spin Hall effect pattern switching in polariton condensates in organic single-crystal microbelts
Jiahuan Ren, Teng Long, Chunling Gu +4
Topological polaritons, combining the robustness of the topological protected edge states to defects and disorder with the strong nonlinear properties of polariton bosons, represen…
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…
