Kagome superconductors from Pomeranchuk fluctuations in charge density wave metals

  title={Kagome superconductors from Pomeranchuk fluctuations in charge density wave metals},
  author={Yu-Ping Lin and Rahul M. Nandkishore},
Motivated by the recent experiments on the kagome metals AV3Sb5 with A = K,Rb,Cs, which see onset of charge density wave (CDW) order at ∼ 100 K and superconductivity at ∼ 1 K, we explore the onset of superconductivity, taking the perspective that it descends from a parent CDW state. In particular, we propose that the pairing comes from the Pomeranchuk fluctuations of the reconstructed Fermi surface in the CDW phase. This scenario naturally explains the large separation of energy scale from the… Expand
