Recent advances in the combination of nonlinearity and exceptional points
Kai Bai, Chen Lin, Jia-Zheng Li +1
The exotic physics emerging at singularities has long attracted intense theoretical and experimental attention. In non-Hermitian systems, exceptional points (EPs), unique spectral…
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…
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…
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…
