Topological superconductivity at the edge of transition metal dichalcogenides
Gang Xu, Jing Wang, Binghai Yan +1
Time-reversal breaking topological superconductors are new states of matter which can support Majorana zero modes at the edge. In this paper, we propose a new realization of one-di…
Universal Scaling of Quantum Anomalous Hall Plateau Transition
Jing Wang, Biao Lian, Shou-Cheng Zhang
We study the critical properties of the quantum anomalous Hall (QAH) plateau transition in magnetic topological insulators. We introduce a microscopic model for the plateau transit…
Topological States in Ferromagnetic CdO/EuO Superlattices and Quantum Wells
Haijun Zhang, Jing Wang, Gang Xu +2
Based on ab initio calculations, we demonstrate that the ferromagnetic CdO/EuO superlattice is a simple Weyl semimetal with two linear Weyl nodes in the Brillouin zone, and the cor…
Anomalous Edge Transport in the Quantum Anomalous Hall State
Jing Wang, Biao Lian, Haijun Zhang +1
We predict by first-principles calculations that thin films of Cr-doped (Bi,Sb)Te magnetic topological insulator have gapless non-chiral edge states coexisting with the chi…
Large-gap quantum spin Hall insulators in tin films
Yong Xu, Binghai Yan, Hai-Jun Zhang +5
The search of large-gap quantum spin Hall (QSH) insulators and effective approaches to tune QSH states is important for both fundamental and practical interests. Based on first-pri…
Quantum Anomalous Hall Effect with Higher Plateaus
Jing Wang, Biao Lian, Haijun Zhang +2
Quantum anomalous Hall (QAH) effect in magnetic topological insulators is driven by the combination of spontaneous magnetic moments and spin-orbit coupling. Its recent experimental…
