d-Wave pair density wave superconductivity in a two-orbital model
Two-orbital models with interorbital t-J or t-V interactions exhibit incommensurate d_xy pair density wave superconductivity driven by interband pairing, confirmed by RPA and strong-coupling hard-core pair calculations showing period-2 PDW over wide fillings.
