Supersolid phases of dipolar systems - Massimo Boninsegni

The supersolid phase of matter, in which both density and superfluid order coexist, has been long sought, unsuccessfully, in crystals of helium. in recent times, the experimental effort has turned to assemblies of cold atoms or molecules featuring a permanent dipole moment. The long-range and anisotropic character of the interaction pave the way to the stabilization of novel, exotic phases of matter, including a supersolid one, consisting of parallel arrays of filaments. In this talk, results of first principle theoretical studies of the phase diagram of dipolar bosons carried out in our group will be reviewed, with particular emphasis on aspects directly connected to very recent experimental observations.
