Cs V 3 Sb 5 : A Z 2 Topological Kagome Metal with a Superconducting Ground State
Brenden R. Ortiz,Samuel M. L. Teicher,Yong Hu,Julia L. Zuo,P. M. Sarte,Emily C. Schueller,A. M. Milinda Abeykoon,M. J. Krogstad,Stephan Rosenkranz,Raymond Osborn,Ram Seshadri,Leon Balents,Junfeng He,Stephen D. Wilson +13 more
TL;DR: The electronic properties of CsV_{3}Sb_{5} are presented, demonstrating bulk superconductivity in single crystals with a T_{c}=2.5 K, and the implications for the formation of unconventional super conductivity in this material are discussed.
Journal ArticleDOI

TL;DR: In this paper, a new kagome prototype structure is presented, which is based on vanadium, with the Fermi level in close proximity to several Dirac points.
Journal ArticleDOI
Giant, unconventional anomalous Hall effect in the metallic frustrated magnet candidate, KV3Sb5.

TL;DR: KV3Sb5 shows enhanced skew scattering that scales quadratically, not linearly, with the longitudinal conductivity, possibly arising from the combination of highly conductive Dirac quasiparticles with a frustrated magnetic sublattice, which allows the possibility of reaching an anomalous Hall angle of 90° in metals.
Journal ArticleDOI

TL;DR: In this paper, the authors used high-resolution scanning tunnelling microscopy to discover an unconventional chiral charge order in a kagome material, KV3Sb5, with both a topological band structure and a superconducting ground state.
Journal ArticleDOI

Jun Yan,Prashun Gorai,Prashun Gorai,Brenden R. Ortiz,Samuel A. Miller,Scott A. Barnett,Thomas O. Mason,Vladan Stevanović,Vladan Stevanović,Eric S. Toberer,Eric S. Toberer +10 more
TL;DR: In this paper, a semi-empirical approach rooted in first-principles calculations that allows relatively simple computational assessment of the intrinsic bulk material properties which govern the thermoelectric figure of merit (zT) is presented.
