Observation of excitons bound by antiferromagnetic correlations by Omar Mehio, Yuchen Han, Xinwei Li, Honglie Ning, Zach Porter, Stephen D. Wilson, David Hsieh

“…Two-dimensional Mott insulators host antiferromagnetic (AFM) correlations that are predicted to enhance the attractive interaction between empty (holons) and doubly occupied (doublons) sites, creating a novel pathway for exciton formation. …”

Insulator phases of Bose-Fermi mixtures induced by intraspecies next-neighbor interactions by Felipe Gómez-Lozada, Roberto Franco, Jereson Silva-Valencia

“…Exploring the problem's parameters, we observed that the nearest-neighbor interaction could favor or harm the well-known mixed Mott and spin-selective Mott insulators. We also found the emergence of three unusual insulating states with charge density wave (CDW) structures in which the orders of the carriers are out of phase between each other. …”
