Wannier-type photonic higher-order topological corner states induced solely by gain and loss
Ya-Jie Wu, Chao-Chen Liu, Junpeng Hou
Photonic crystals have provided a controllable platform to examine excitingly new topological states in open systems. In this work, we reveal photonic topological corner states in…
Symmetry-protected localized states at defects in non-Hermitian systems
Ya-Jie Wu, Junpeng Hou
Understanding how local potentials affect system eigenmodes is crucial for experimental studies of nontrivial bulk topology. Recent studies have discovered many exotic and highly n…
In-plane Zeeman field induced Majorana corner and hinge modes in an -wave superconductor heterostructure
Ya-Jie Wu, Junpeng Hou, Yun-Mei Li +3
Second-order topological superconductors host Majorana corner and hingemodes in contrast to conventional edge and surface modes in two and three dimensions. However, the realizatio…
Non-Hermitian Photonics based on Charge-Parity Symmetry
Junpeng Hou, Zhitong Li, Qing Gu +1
Parity-time () symmetry, originally conceived for non-Hermitian open quantum systems, has opened an excitingly new avenue for the coherent control of light. By tailor…
Experimental realization of a non-magnetic one-way spin switch
M. E. Mossman, Junpeng Hou, Xi-Wang Luo +2
Controlling magnetism through non-magnetic means is highly desirable for future electronic devices, as such means typically have ultra-low power requirements and can provide cohere…
