Large shift current, Zak phase and unconventional nature in Se and Te
Ruihan Zhang, Junze Deng, Yan Sun +3
Recently, unconventional materials (or obstructed atomic insulators) have attracted much attention owing to the unconventional feature of mismatch between Wannier centers and atomi…
Hierarchy of quasi-symmetries and degeneracies in chiral crystal materials CoSi
Lun-Hui Hu, Chunyu Guo, Yan Sun +5
In materials, certain approximated symmetry operations can exist in a lower-order approximation of the effective model but are good enough to influence the physical responses of th…
Anisotropic linear and nonlinear charge-spin conversion in topological semimetal SrIrO3
Bin Lao, Peitao Liu, Xuan Zheng +11
Over the past decade, utilizing spin currents in the linear response of electric field to manipulate magnetization states via spin-orbit torques (SOTs) is one of the core concepts…
Large spin Hall conductivity and excellent hydrogen evolution reaction activity in unconventional PtTe1.75 monolayer
Dexi Shao, Junze Deng, Haohao Sheng +6
Two-dimensional (2D) materials have gained lots of attention due to the potential applications. In this work, we propose that based on first-principles calculations, the (2…
Weyl nodal ring states and Landau quantization with very large magnetoresistance in square-net magnet EuGa
Shiming Lei, Kevin Allen, Jianwei Huang +17
Magnetic topological semimetals (TSMs) allow for an effective control of the topological electronic states by tuning the spin configuration, and therefore are promising materials f…
Coexistence of Weyl semimetal and Weyl nodal loop semimetal phases in a collinear antiferromagnet
Jie Zhan, Jiangxu Li, Wujun Shi +2
Antiferromagnets (AFMs) with anomalous quantum responses have lead to new progress for the understanding of their magnetic and electronic structures from symmetry and topology poin…
