Common sublattice-pure van Hove singularities in the kagome superconductors VSb ( = K, Rb, Cs)
Yujie Lan, Yuhao Lei, Congcong Le +7
Kagome materials offer a versatile platform for exploring correlated and topological quantum states, where van Hove singularities (VHSs) play a pivotal role in driving electronic i…
Comparative Raman study of Ruddlesden-Popper nickelates and the monolayer-trilayer polymorph
Vignesh Sundaramurthy, Abhi Suthar, Pascal Puphal +12
Ruddlesden-Popper (RP) nickelates have attracted intense interest following the discovery of superconductivity in several members of the series, including bilayer (BL) LaNi…
Topological electron and phonon flat bands in novel kagome superconductor XPd5 (X=Ca, Sr, Ba)
Jiefeng Ye, Zhigao Huang, Xianxin Wu +1
Fermionic and bosonic localized states induced by geometric frustration in the kagome lattice provide a distinctive research platform for investigating emergent exotic quantum phen…
Out-of-plane bond-order phase, superconductivity, and their competition in the -- model: Possible implications for bilayer nickelates
MatÃas Bejas, Xianxin Wu, Debmalya Chakraborty +2
Almost four decades of intense research have been invested to study the physics of high-T cuprate superconductors. The recent discovery of high-T superconductivity in press…
Topological electronic structure and electronic nematicity in candidate kagome superconductors, ATiBi (A = Rb, Cs)
Yong Hu, Congcong Le, Xianxin Wu +1
The newly discovered family of titanium-based kagome metals, ATiBi (where A can be Rb or Cs), has been found to exhibit non-trivial band topology and fascinating electr…
