Crystalline Solutions of Kohn-Sham Equations in the Fractional Quantum Hall Regime
Yayun Hu, Yang Ge, Jian-Xiao Zhang +1
A Kohn-Sham density functional approach has recently been developed for the fractional quantum Hall effect, which maps the strongly interacting electrons into a system of weakly in…
Disordered Quantum Transport in Quantum Anomalous Hall Insulator-Superconductor Junctions
Jian-Xiao Zhang, Chao-Xing Liu
In this communication, we numerically studied disordered quantum transport in a quantum anomalous Hall insulator-superconductor junction based on the effective edge model approach.…
Concurrence of Quantum Anomalous Hall and Topological Hall Effects in Magnetic Topological Insulator Sandwich Heterostructures
Jue Jiang, Di Xiao, Fei Wang +13
The quantum anomalous Hall (QAH) effect is a quintessential consequence of non-zero Berry curvature in momentum-space. The QAH insulator harbors dissipation-free chiral edge states…
Topological Hall Effect in Magnetic Topological Insulator Films
Jian-Xiao Zhang, Domenico Andreoli, Jiadong Zang +1
Geometric Berry phase can be induced either by spin-orbit coupling, giving rise to the anomalous Hall effect in ferromagnetic materials, or by chiral spin texture, such as skyrmion…
A valley valve and electron beam splitter
Jing Li, Rui-Xing Zhang, Zhenxi Yin +5
Developing alternative paradigms of electronics beyond silicon technology requires the exploration of fundamentally new physical mechanisms, such as the valley specific phenomena i…
