Evolution of spectral topology in one-dimensional long-range nonreciprocal lattices
Qi-Bo Zeng, Rong Lü
We investigate the spectral topology of one-dimensional lattices where the nonreciprocal hoppings within the nearest neighboring sites are the same. For the purely off-diagon…
On the anomalous low-resistance state and exceptional Hall component in hard-magnetic Weyl nanoflakes
Qingqi Zeng, Gangxu Gu, Gang Shi +7
Magnetic topological materials, which combine magnetism and topology, are expected to host emerging topological states and exotic quantum phenomena. In this study, with the aid of…
Topological phases and Anderson localization in off-diagonal mosaic lattices
Qi-Bo Zeng, Rong Lü
We introduce a one-dimensional lattice model whose hopping amplitudes are modulated for equally spaced sites. Such mosaic lattice exhibits many interesting topological and localiza…
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…
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…
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…
