High-order van Hove singularities and nematic instability in the kagome superconductor CsTiBi
Bikash Patra, Amrita Mukherjee, Bahadur Singh
ATiBi (A = Cs or Rb) are emerging topological kagome metals that exhibit superconductivity and nematicity without intertwining translational symmetry-breaking charge orders…
