Observation of Co-propagating Chiral Zero Modes in Magnetic Photonic Crystals
Zhongfu Li, Shaojie Ma, Shuwei Li +6
Topological singularities, such as Weyl points and Dirac points, can give rise to unidirectional propagation channels known as chiral zero modes (CZMs) when subject to a magnetic f…
Diverse surface waves supported by bianisotropic metasurfaces
Oubo You, Wenlong Gao, Yachao Liu +2
Surface waves supported by structured metallic surfaces, i.e. metasurfaces, have drawn wide attention recently. They are promising for various applications ranging from integrated…
Quantized photonic spin Hall effect in graphene
Liang Cai, Mengxia Liu, Shizhen Chen +4
We examine the photonic spin Hall effect (SHE) in a graphene-substrate system with the presence of external magnetic field. In the quantum Hall regime, we demonstrate that the in-p…
