Momentum Structure of Superconductivity and Sublattice Effects from Quasiparticle Interference in CsVSb

Aaron G. Greenberg, Xinze Yang, Junze Deng +11

Quantum interference encoded in the sublattice texture of kagome Bloch wavefunctions has been widely invoked as a route to correlated states, including chiral charge order, unconve…

FeGe as a building block for the kagome 1:1, 1:6:6, and 1:3:5 families: hidden d-orbital decoupling of flat band sectors, effective models and interaction Hamiltonians

Yi Jiang, Haoyu Hu, Dumitru Călugăru +5

The electronic structure and interactions of kagome materials, such as the 1:1 (FeGe) and 1:6:6 (MgFe6Ge6) classes, are complicated and involve many orbitals and bands around the F…
