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…
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…
High-pressure modulation of breathing kagome lattice: Cascade of Lifshitz transitions and evolution of the electronic structure
Marcos V. Gonçalves-Faria, Maxim Wenzel, Yuk Tai Chan +12
The interplay between electronic correlations, density wave orders, and magnetism gives rise to several fascinating phenomena. In recent years, kagome metals have emerged as an exc…
