Cornertronics in Two-Dimensional Second-Order Topological Insulators
Yilin Han, Chaoxi Cui, Xiao-Ping Li +4
Traditional electronic devices rely on the electron's intrinsic degrees of freedom (d.o.f.) to process information. However, additional d.o.f. like the valley, can emerge in the lo…
Upper bound of a band complex
Si Li, Zeying Zhang, Xukun Feng +5
Band structure for a crystal generally consists of connected components in energy-momentum space, known as band complexes. Here, we explore a fundamental aspect regarding the maxim…
Three-dimensional real Chern insulator in bulk -graphyne
Xu-Tao Zeng, Bin-Bin Liu, Fan Yang +4
The real Chern insulator state, featuring nontrivial real Chern number and second-order boundary modes, has been revealed in a few two-dimensional systems. The concept can be exten…
Accurate recipe for predicting valley Linear Weyl phonons in two dimensions
Mingmin Zhong, Haibo Liu, Jianhua Wang +5
The discovery of topological quantum states in two-dimensional (2D) systems is one of the most promising advancements in condensed matter physics. Linear Weyl point (LWP) phonons h…
Berry curvature dipole and nonlinear Hall effect in two-dimensional NbSiTe
Yiwei Zhao, Jin Cao, Zeying Zhang +4
Recent experiments have demonstrated interesting physics in a family of two-dimensional (2D) composition-tunable materials NbSiTe. Here, we show that owing to…
