Fractional-filling Mott domains in two dimensional optical superlattices
Pierfrancesco Buonsante, Vittorio Penna, Alessandro Vezzani
Ultracold bosons in optical superlattices are expected to exhibit fractional-filling insulating phases for sufficiently large repulsive interactions. On strictly 1D systems, the ex…
Analytical mean-field approach to the phase-diagram of ultracold bosons in optical superlattices
P. Buonsante, V. Penna, A. Vezzani
We report a multiple-site mean-field analysis of the zero-temperature phase diagram for ultracold bosons in realistic optical superlattices. The system of interacting bosons is des…
Fractional-filling loophole insulator domains for ultracold bosons in optical superlattices
Pierfrancesco Buonsante, Vittorio Penna, Alessandro Vezzani
The zero-temperature phase diagram of a Bose-Einstein condensate confined in realistic one-dimensional -periodic optical superlattices is investigated. The system of interact…
