Pulse irradiation induces interband electron-electron pair correlations in the EFKM photoexcited states through its internal SU(2) pairing structure, even on nonbipartite lattices with direct band structure.
Here, we implicitly as- sume that the hoppings are finite between sites connected through the primitive translation vectors and the unit cell contains only a single site

Photoinduced electron-electron pairing in the extended Falicov-Kimball model
Pulse irradiation induces interband electron-electron pair correlations in the EFKM photoexcited states through its internal SU(2) pairing structure, even on nonbipartite lattices with direct band structure.
