Transport through Quantum Anomalous Hall Bilayers with Lattice Mismatch
Yan Yu, Yan-Yang Zhang, Si-Si Wang +4
We theoretically investigate quantum transport properties of quantum anomalous Hall bilayers, with arbitrary ratio of lattice constants, i.e., with lattice mismatch. In the simples…
Numerical Study of Disorder on the Orbital Magnetization in Two Dimensions
Si-Si Wang, Yan-Yang Zhang, Ji-Huan Guan +3
The modern theory of orbital magnetization (OM) was developed by using Wannier function method, which has a formalism similar with the Berry phase. In this manuscript, we perform a…
Chebyshev Polynomial Method to Landauer-Büttiker Formula of Quantum Transport in Nanostructures
Yan Yu, Yan-Yang Zhang, Lei Liu +4
Landauer-Büttiker formula describes the electronic quantum transports in nanostructures and molecules. It will be numerically demanding for simulations of complex or large size sys…
Localization Trajectory and Chern-Simons axion coupling for Bilayer Quantum Anomalous Hall Systems
Si-Si Wang, Yan-Yang Zhang, Ji-Huan Guan +3
Quantum anomalous Hall (QAH) multilayers provide a platform of topological materials with high Chern numbers. We investigate the localization routes of bilayer QAH systems with Che…
Barrier tunneling of the Loop-Nodal Semimetal in the Hyperhoneycomb lattice
Ji-Huan Guan, Yan-Yang Zhang, Wei-Er Lu +2
We theoretically investigate the barrier tunneling in the three-dimensional model of the hyperhoneycomb lattice, which is a nodal-line semimetal with a Dirac loop at zero energy. I…
