Observation of emergent Dirac physics at the surfaces of acoustic higher-order topological insulators
Fei Meng, Zhi-Kang Lin, Weibai Li +5
Using three-dimensional (3D) sonic crystals as acoustic higher-order topological insulators (HOTIs), we discover two-dimensional (2D) surface states described by spin-1 Dirac equat…
Dual-Polarization Second-Order Photonic Topological Insulators
Yafeng Chen, Fei Meng, Zhihao Lan +2
Second-order photonic topological insulators that host highly localized corner states resilient to defects, are opening new routes towards developing fascinating photonic devices.…
Multidimensional sound propagation in 3D high-order topological sonic insulator
Fei Meng, Yafeng Chen, Weibai Li +2
High-order topological insulators (TIs) develop the conventional bulk-boundary correspondence theory and rise the interest in searching innovative topological materials. To realize…
Inverse design of higher-order photonic topological insulators
Yafeng Chen, Fei Meng, Yuri Kivshar +2
Topological photonics revolutionizes some of the traditional approaches to light propagation and manipulation, and it provides unprecedented means for developing novel photonic dev…
