Berry-Curvature Exchange Induced Anderson Localization in Large-Chern-Number Quantum Anomalous Hall Effect
Hui Yang, Junjie Zeng, Yulei Han +1
We theoretically investigate the localization mechanism of quantum anomalous Hall Effect (QAHE) with large Chern numbers in bilayer graphene and magnetic topological…
Mesoscopic Electronic Transport in Twisted Bilayer Graphene
Yulei Han, Yafei Ren, Xinlong Dong +3
We numerically investigate the electronic transport properties between two mesoscopic graphene disks with a twist by employing the density functional theory coupled with non-equili…
Finite-Size Effects in the Dynamic Conductivity and Faraday Effect of Quantum Anomalous Hall Insulators
Junjie Zeng, Tao Hou, Zhenhua Qiao +1
We theoretically study the finite-size effects in the dynamical response of a quantum anomalous Hall insulator in the disk geometry. Semi-analytic and numerical results are obtaine…
Micro-Structuring, Ablation and Defect Generation in Graphene with Femtosecond Pulses
Andres Vasquez, Panagis Samolis, Junjie Zeng +1
Femtosecond micromachining offers a contact-free and mask-less technique for material patterning. With ultrafast laser irradiation, permanent modifications to the properties of sin…
Universal Current Correlations Induced by the Majorana and Fermionic Andreev Bound States
Kunhua Zhang, Xinlong Dong, Junjie Zeng +2
Due to their nonlocality, Majorana bound states have been proposed to induce current-current correlations (CCCs) that are completely different from those induced by low-energy ferm…
Current partition at zero-line intersection of quantum anomalous Hall topologies
Yafei Ren, Junjie Zeng, Ke Wang +2
At the interface between two-dimensional materials with different topologies, topologically protected one-dimensional states (also named as zero-line modes) arise. Here, we focus o…
