Hydrogen-induced magnetism in graphene: a simple effective model description
Shuai Li, Rui Yu, Jin-Hua Gao +1
Hydrogen adatoms induced magnetic moment on graphene has been observed in atomic scale in a recent experiment [Gonzalez-Herrero et al., Science 352, 437 (2016)]. Here, we demonstra…
Quantized thermal Hall conductance from edge current calculations in lattice models
Wei Tang, X. C. Xie, Lei Wang +1
The quantized thermal Hall effect is an important probe for detecting chiral topological order and revealing the nature of chiral gapless edge states. The standard Kubo formula app…
Numerical study of the negative nonlocal resistance and the backflow current in a ballistic graphene system
Zibo Wang, Haiwen Liu, Hua Jiang +1
Besides the giant peak of the nonlocal resistance , an anomalous negative value of has been observed in graphene systems, while its formation mechanism is not quit…
Emergent Topological Invariant and Robust Helical Edge States in Two-Dimensional Topological Metals
Chui-Zhen Chen, Hua Jiang, Dong-Hui Xu +1
In this work, we study the disorder effect on topological metals that support a pair of helical edge modes deeply embedded inside the gapless bulk states. Strikingly, we predict th…
Flat band localization due to self-trapped orbital
Zhen Ma, Wei-Jin Chen, Yuntian Chen +2
We discover a new wave localization mechanism in a periodic system without any disorder, which can produce a novel type of perfect flat band and is distinct from the known localiza…
