Hi,

I would like to study the ground-state phase transition and structure factor of the extended Bose-Hubbard model on a frustrated 2D lattice such as star lattice or square-Kagome lattice.
Is it possible to use DSQSS package to do that?

If t (hopping constant) is positive, yes -- the negative sign problem does not appear.
