Beyond kagome: -bands in kagome metals
Alexander A. Tsirlin, Ece Uykur
We review recent studies on quantum materials where transition-metal atoms give rise to -bands typical of kagome metals. Using examples from several material families - AVSb…
Is ruthenium dioxide altermagnet?
Alexander A. Tsirlin, Ece Uykur, Oleg Janson
Ruthenium dioxide was named as one of the first and most promising altermagnetic candidates with -wave symmetry. We summarize key findings for this material and critically discu…
Optical conductivity and band gap in the double-Weyl candidate SrSi2 at ambient pressure
L. Z. Maulana, A. A. Tsirlin, E. Uykur +4
We probe the possible double-Weyl state in cubic SrSi2 using optical spectroscopy. The complex optical conductivity was measured in a frequency range from 70 to 22 000 cm-1 at temp…
Interplay of - and -states in RbTiBi and CsTiBi flat-band kagome metals
M. Wenzel, E. Uykur, A. A. Tsirlin +4
Shifting the Fermi level of the celebrated (135) compounds into proximity of flat bands strongly enhances electronic correlations and severely affects the formation of de…
Pressure-tuned spin chains in brochantite, CuSO(OH)
Victoria A. Ginga, Bin Shen, Ece Uykur +3
Using high-pressure single-crystal x-ray diffraction combined with thermodynamic measurements and density-functional calculations, we uncover the microscopic magnetic model of the…
Pressure-induced strange metal phase in a metallic kagome ferromagnet
Bin Shen, Feng Du, Franziska Breitner +4
Strange metallicity with -linear electrical resistance preceding high- superconductivity remains an enigmatic, yet crucial, signature of correlation physics. Using electric…
