Numerical Investigation of Localization in Two-Dimensional Quasiperiodic Mosaic Lattice
Hui-Hui Wang, Si-Si Wang, Yan Yu +5
A one-dimensional lattice model with mosaic quasiperiodic potential is found to exhibit interesting localization properties, e.g., clear mobility edges [Y. Wang et al., Phys. Rev.…
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…
Effects of Boundary on Orbital Magnetization for a Bilayer System with Different Chern Numbers
Si-Si Wang, Yan Yu, Ji-Huan Guan +3
The real space formalism of orbital magnetization (OM) is an average of the local OM over some appropriate region of the system. Previous studies prefer a bulk average (i.e., witho…
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…
