Family of third-order topological insulators from Su-Schrieffer-Heeger stacking
Xun-Jiang Luo, Jia-Zheng Li, Meng Xiao +1
We construct a family of chiral symmetry-protected third-order topological insulators by stacking Su-Schrieffer-Heeger (SSH) chains and provide a unified topological characterizati…
Photonic realization of chiral hinge states in a Chern-insulator stack
Han-Rong Xia, Jia-Zheng Li, Si-Yu Yuan +1
Higher-order topological insulators, as a novel family of topological phases, are a hot frontier in condensed matter physics due to their adherence to unconventional bulk-boundary…
Exact Universal Characterization of Chiral-Symmetric Higher-Order Topological Phases
Jia-Zheng Li, Xun-Jiang Luo, Fengcheng Wu +1
Utilizing Bott index vectors formulated through a series of polynomials of position operators under open boundary conditions, we establish a universal, rigorous, and complete corre…
