Mode-resolved reciprocal space mapping of electron-phonon interaction in the Weyl semimetal candidate Td-WTe
P. Hein, S. Jauernik, H. Erk +5
The selective excitation of coherent phonons provides unique capabilities to control fundamental properties of quantum materials on ultrafast time scales. For instance, in the pres…
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…
Thickness dependence of the anomalous Nernst effect and the Mott relation of Weyl-semimetal Co2MnGa thin films
Gyu-Hyeon Park, Helena Reichlova, Richard Schlitz +12
We report a robust anomalous Nernst effect in Co2MnGa thin films in the thickness regime between 20 and 50 nm. The anomalous Nernst coefficient varied in the range of -2.0 to -3.0…
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…
A Charge-Density-Wave Topological Semimetal
Wujun Shi, Benjamin J. Wieder, H. L. Meyerheim +14
Topological physics and strong electron-electron correlations in quantum materials are typically studied independently. However, there have been rapid recent developments in quantu…
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…
