Implication

Theoretical study of electronic structure in La1-xSrxNiO2, showing hole distribution and hybridization effects.

Key Points

  • Holes are equally distributed between Ni-3d and interstitial-s orbitals in La1-xSrxNiO2.
  • The coupling between interstitial-s and Ni-3d orbitals affects electronic correlation significantly.
  • ARPES data supports the orbital-selective renormalization in the doping level analysis.
  • Interstitial-s orbital acts as a charge donator, enhancing correlation in Ni-3d orbitals.
