Superfluid, solid, and supersolid phases of dipolar bosons in a quasi-one-dimensional optical lattice

Superfluid, solid, and supersolid phases of dipolar bosons in a quasi-one-dimensional optical lattice

We discuss a model of dipolar bosons trapped in a weakly coupled planar array of one-dimensional tubes. We consider the situation where the dipolar moments are aligned by an external field, and we find a rich phase diagram as a function of the angle of this field exhibiting quantum phase …
