Orientation-Dependent Universality of Spin-Transport Fluctuations in Two-Dimensional Altermagnets
Yihan Zhang, Zheng Qin, Donghui Xu +3
Universal conductance fluctuations are conventionally organized by symmetry class, but crystalline anisotropy introduces additional structure in spin transport. Here we demonstrate…
Higher-Order Band Topology in Twisted Bilayer Kagome Lattice
Xiaolin Wan, Junjie Zeng, Ruixiang Zhu +3
Topologically protected corner states serve as a key indicator for two-dimensional higher-order topological insulators, yet they have not been experimentally identified in realisti…
Photoinduced High-Chern-Number Quantum Anomalous Hall Effect from Higher-Order Topological Insulators
Xiaolin Wan, Zhen Ning, Dong-Hui Xu +2
Quantum anomalous Hall (QAH) insulators with high Chern number host multiple dissipationless chiral edge channels, which are of fundamental interest and promising for applications…
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 (…
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…
Weyl nodes with higher-order topology in an optically driven nodal-line semimetal
Xiu-Li Du, Rui Chen, Rui Wang +1
Creating and manipulating topological states is a key goal of condensed matter physics. Periodic driving offers a powerful method to manipulate electronic states, and even to creat…
