Comprehensive scan for nonmagnetic Weyl semimetals with nonlinear optical response
Qiunan Xu, Yang Zhang, Klaus Koepernik +4
As the development of topological band theory, comprehensive databases about time reversal and crystalline symmetries protected nonmagnetic topological materials were developed via…
Spin-orbitronic materials with record spin-charge conversion from high-throughput ab initio calculations
Yang Zhang, Qiunan Xu, Klaus Koepernik +5
The spin Hall effect (SHE) is an important spintronics phenomenon, which allows transforming a charge current into a spin current and vice versa without the use of magnetic materia…
Signatures for half-metallicity and nontrivial surface states in a Kagome-lattice magnetic Weyl semimetal CoSnS
Lin Jiao, Qiunan Xu, Yeryun Cheon +4
Weyl semimetals with time reversal symmetry breaking are expected to show various fascinating physical behaviors, such as intrinsic giant anomalous Hall effect, chiral anomaly effe…
Surface states in bulk single crystal of topological semimetal CoSnS towards water oxidation
Guowei Li, Qiunan Xu, Wujun Shi +16
The band inversion in topological phase matters bring exotic physical properties such as the emergence of a topologically protected surface states. They strongly influence the surf…
Fermi-arc diversity on surface terminations of the magnetic Weyl semimetal Co3Sn2S2
Noam Morali, Rajib Batabyal, Pranab Kumar Nag +7
Bulk-surface correspondence in Weyl semimetals assures the formation of topological "Fermi-arc" surface bands whose existence is guaranteed by bulk Weyl nodes. By investigating thr…
Large anomalous Hall and Nernst effect from nodal line symmetry breaking in FeMnX (X=P,As,Sb)
Jonathan Noky, Claudia Felser, Yan Sun
A large Berry curvature in the vicinity of the Fermi energy is required in order to obtain a large anomalous Hall and Nernst effect. This Berry curvature can be induced by Weyl poi…
