Large anomalous Hall conductivity in Weyl ferrimagnet CsCoS predicted by density-functional calculations
Gang Bahadur Acharya, Manuel Richter, Klaus Koepernik +1
The identification of topological Weyl semimetals has recently gained considerable attention. Here, we report the results of density-functional theory calculations regarding the ma…
Symmetry Conserving Maximally Projected Wannier Functions
K. Koepernik, O. Janson, Yan Sun +1
To obtain a local description from highly accurate density functional theory codes that are based on modified plane wave bases, a transformation to a local orthonormal Wannier func…
Prediction of unconventional magnetism in doped FeSb2
I. I. Mazin, K. Koepernik, M. D. Johannes +2
It is commonly believed that in typical collinear antiferromagnets, with no net magnetization, the energy bands are spin-(Kramers-degenerate. The opposite case is usually associate…
Sixfold fermion near the Fermi level in cubic PtBi2
S. Thirupathaiah, Y. S. Kushnirenk, K. Koepernik +6
We show that the cubic compound PtBi2, is a topological semimetal hosting a sixfold band touching point in close proximity to the Fermi level. Using angle-resolved photoemission sp…
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…
