Design of Antiferromagnetic Second-order Band Topology with Rotation Topological Invariants in Two Dimensions
Fangyang Zhan, Zheng Qin, Dong-Hui Xu +3
The existence of fractionally quantized topological corner states serves as a key indicator for two-dimensional second-order topological insulators (SOTIs), yet has not been experi…
The One-dimensional Chiral Anomaly and its Disorder Response
Zheng Qin, Dong-Hui Xu, Zhen Ning +1
The condensed-matter realization of chiral anomaly has attracted tremendous interest in exploring unexpected phenomena of quantum field theory. Here, we show that one-dimensional (…
Robustness of Half-Integer Quantized Hall Conductivity against Disorder in an Anisotropic Dirac Semimetal with Parity Anomaly
Zhen Ning, Xianyong Ding, Dong-Hui Xu +1
Two-dimensional Dirac semimetals with a single massless Dirac cone exhibit the parity anomaly. Usually, such a kind of anomalous topological semimetallic phase in real materials is…
Floquet Weyl semimetal phases in light-irradiated higher-order topological Dirac semimetals
Zi-Ming Wang, Rui Wang, Jin-Hua Sun +2
Floquet engineering, the concept of tailoring a system by a periodic drive, is increasingly exploited to design and manipulate topological phases of matter. In this work, we study…
Tailoring Quadrupole Topological Insulators with Periodic Driving and Disorder
Zhen Ning, Bo Fu, Dong-Hui Xu +1
The quadrupole topological insulator (QTI) has attracted intense studies as a prototype of symmetry-protected higher-order topological phases of matter with a quantized quadrupole…
