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…
Boundary topological insulators and superconductors of Altland-Zirnbauer tenfold classes
Xun-Jiang Luo, Fengcheng Wu
In a class of systems, there are gapped boundary-localized states described by a boundary Hamiltonian. The topological classification of gapped boundary Hamiltonians, same as the s…
Characterization of higher-order topological superconductors using Bott indices
Xun-Jiang Luo, Jia-Zheng Li, Meng Xiao +1
The abundance of bulk and boundary topologies in higher-order topological phases offer remarkable tunability and diversity to boundary states but also pose a challenge to their uni…
Quantum simulation of honeycomb lattice model by high-order moiré pattern
Qiang Wan, Chunlong Wu, Xun-Jiang Luo +11
Moiré superlattices have become an emergent solid-state platform for simulating quantum lattice models. However, in single moiré device, Hamiltonians parameters like lattice consta…
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…
