Web28 aug. 2024 · Experimental realization of a Weyl exceptional ring. Alexander Cerjan, Sheng Huang, Kevin P. Chen, Yidong Chong, Mikael C. Rechtsman. Weyl points are isolated degeneracies in reciprocal space that are monopoles of the Berry curvature. This topological charge makes them inherently robust to Hermitian perturbations of the system. Web14 sep. 2024 · Here, we report high-visibility quantum interference of two single-photon topological boundary states in a photonic waveguide array. We engineered a time-varying Hamiltonian, controlling the band structure of the device and the spatial isolation of the topological states to implement a 50:50 beamsplitter.
