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.
Chiral crystals with screw symmetry undergo a spontaneous spin-selective structural phase transition driven by handedness-dependent phonon renormalization, producing helical spin density waves and chiral lattice distortions.
