Singlet Mott State Simulating the Bosonic Laughlin Wave Function
Biao Lian, Shou-Cheng Zhang
We study properties of a class of spin singlet Mott states for arbitrary spin S bosons on a lattice, with particle number per cite n=S/l+1, where l is a positive integer. We show t…
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…
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…
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…
Synthetic Gauge Field with Highly Magnetic Lanthanide Atoms
Xiaoling Cui, Biao Lian, Tin-Lun Ho +2
We present a scheme for generating a synthetic magnetic field and spin-orbit coupling via Raman coupling in highly magnetic lanthanide atoms such as dysprosium. Employing these ato…
