Theory of potential impurity scattering in pressurized superconducting La3Ni2O7

Disordered bilayer modelWe consider a bilayer Hamiltonian with point-like non-magnetic impurities \({{{\mathcal{H}}}}={{{{\mathcal{H}}}}}_{0}+{{{{\mathcal{H}}}}}_{{{{\rm{int}}}}}+{{{{\mathcal{H}}}}}_{{{{\rm{dis}}}}}\), where the interaction term gives rise to an…
