    Mar 22, 2024Motivated by the recent progress in realizing and controlling extended Bose-Hubbard systems using excitonic or atomic devices, the present Letter theoretically investigates the case of a two-band Bose-Hubbard chain with nearest-neighbor interactions. Specifically, this study concentrates on the scenario where, due to the interactions, one band supports a density-wave phase, i.e., a correlated ...

    COMPETING ORDER IN TWO-BAND BOSE-HUBBARD … PHYSICAL REVIEW B 109, L100507 (2024) FIG. 2. The ground-state phase diagram of an unpolarized system (L = 40) at unit filling with Ua = 5,V a = 4andU b = 1,V b = 0.5, with J a = J b = 1 being the unit of energy. With this choice, band A is in the DW regime, whereas band B is SF.

    FIG. 1. Five possible states at unit-filling with negligibly small hopping. These states appear depending on the competition of interactions. In the case of phase-separation (PS), the two subsystems may form n = 2 Mott states (as shown here), or, if V > 3U , density wave patterns with 4-fold occupied sites (not shown). - "Competing order in two-band Bose-Hubbard chains with extended-range ...
