Electrically Tunable Magnetism in Magnetic Topological Insulators
Jing Wang, Biao Lian, Shou-Cheng Zhang
The external controllability of the magnetic properties in topological insulators would be important both for fundamental and practical interests. Here we predict the electric-fiel…
Quantum Anomalous Hall Effect in Magnetic Insulator Heterostructure
Gang Xu, Jing Wang, Claudia Felser +2
Based on ab initio calculations, we predict that a monolayer of Cr-doped (Bi,Sb)2Te3 and GdI2 heterostructure is a quantum anomalous Hall insulator with a non-trivial band gap up t…
Quantum anomalous Hall effect in magnetic topological insulators
Jing Wang, Biao Lian, Shou-Cheng Zhang
The search for topologically non-trivial states of matter has become an important goal for condensed matter physics. Here, we give a theoretical introduction to the quantum anomalo…
Quantum Spin Hall and Quantum Anomalous Hall States Realized in Junction Quantum Wells
Haijun Zhang, Yong Xu, Jing Wang +1
Both quantum spin Hall and quantum anomalous Hall states are novel states of quantum matter with promising applications. We propose junction quantum wells comprising II-VI, III-V o…
Two-dimensional time-reversal-invariant topological superconductivity in a doped quantum spin Hall insulator
Jing Wang, Yong Xu, Shou-Cheng Zhang
Time-reversal-invariant topological superconductors have a full paring gap in the bulk and gapless Majorana states at the edge or on the surface. Here, we theoretically propose top…
