The Berry curvature dipole in Weyl semimetal materials: an ab initio study
Yang Zhang, Yan Sun, Binghai Yan
Noncentrosymmetric metals are anticipated to exhibit a photocurrent in the nonlinear optical response caused by the Berry curvature dipole in momentum space. Weyl semimetals (…
Hidden type-II Weyl points in the Weyl semimetal NbP
Shu-Chun Wu, Yan Sun, Claudia Felser +1
As one of Weyl semimetals discovered recently, NbP exhibits two groups of Weyl points with one group lying inside the plane and the other group staying away from this plane…
Superconductivity in alkaline earth metal-filled skutterudites BaxIr4X12 (X = As, P)
Yanpeng Qi, Hechang Lei, Jiangang Guo +4
We report superconductive iridium pnictides BaxIr4X12 (X = As and P) with a filled skutterudite structure, demonstrating that Ba filling dramatically alters their electronic proper…
Tunable Weyl and Dirac states in the nonsymmorphic compound
Leslie M. Schoop, Andreas Topp, Judith Lippmann +14
Recent interest in topological semimetals has lead to the proposal of many new topological phases that can be realized in real materials. Next to Dirac and Weyl systems, these incl…
Update of the trigger system of the PandaX-II experiment
Qinyu Wu, Xun Chen, Xiangdong Ji +8
PandaX-II experiment is a dark matter direct detection experiment using about half-ton of liquid xenon as the sensitive target. The electrical pulses detected by photomultiplier tu…
Symmetry Demanded Topological Nodal-line Materials
Shuo-Ying Yang, Hao Yang, Elena Derunova +3
The realization of Dirac and Weyl physics in solids has made topological materials one of the main focuses of condensed matter physics. Recently, the topic of topological nodal lin…
