Exotic Haldane Superfluid Phase of Soft-Core Bosons in Optical Lattices
Jian-Ping Lv, Z. D. Wang
We propose to realize an exotic Haldane superfluid (HSF) phase in an extended Bose-Hubbard model on the two-leg ladder (i.e., a two-species mixture of interacting bosons). The prop…

Coulomb liquid phases of bosonic cluster Mott insulators on a pyrochlore lattice
Jian-Ping Lv, Gang Chen, Youjin Deng +1
Employing large-scale quantum Monte Carlo simulations, we reveal the full phase diagram of the extended Hubbard model of hard-core bosons on the pyrochlore lattice with partial fil…
