Topological Superconductors in One-Dimensional Mosaic Lattices
Qi-Bo Zeng, Rong Lü, Li You
We study topological superconductor in one-dimensional (1D) mosaic lattice whose on-site potentials are modulated for equally spaced sites. When the system is topologically nontriv…
Ultra-efficient magnetism modulation in a Weyl ferromagnet by current-assisted domain wall motion
Qiuyuan Wang, Yi Zeng, Kai Yuan +10
Flexible and efficient manipulation of magnetic configurations can be challenging. In the design of practical devices, achieving a high effective magnetic field with a low working…
33% Giant Anomalous Hall Current Driven by both Intrinsic and Extrinsic Contributions in Magnetic Weyl Semimetal Co3Sn2S2
Jianlei Shen, Qingqi Zeng, Shen Zhang +8
Anomalous Hall effect (AHE) can be induced by intrinsic mechanism due to the band Berry phase and extrinsic one arising from the impurity scattering. The recently discovered magnet…
Hinge solitons in three-dimensional second-order topological insulators
Yu-Liang Tao, Ning Dai, Yan-Bin Yang +2
A second-order topological insulator in three dimensions refers to a topological insulator with gapless states localized on the hinges, which is a generalization of a traditional t…
On the anisotropies of magnetization and electronic transport of magnetic Weyl semimetal Co3Sn2S2
Jianlei Shen, Qingqi Zeng, Shen Zhang +8
Co3Sn2S2, a quasi-two-dimensional system with kagome lattice, has been found as a magnetic Weyl semimetal recently. In this work, the anisotropies of magnetization and transport pr…
Winding Numbers and Generalized Mobility Edges in Non-Hermitian Systems
Qi-Bo Zeng, Yong Xu
The Aubry-André-Harper (AAH) model with a self-dual symmetry plays an important role in studying the Anderson localization. Here we find a self-dual symmetry determining the quantu…
