Hexatic, Wigner Crystal, and Superfluid Phases of Dipolar Bosons
Kaushik Mitra, C. J. Williams, C. A. R. Sá de Melo
The finite temperature phase diagram of two-dimensional dipolar bosons versus dipolar interaction strength is discussed. We identify the stable phases as dipolar superfluid (DSF),…

Vortices, antivortices and superfluid shells separating Mott-insulating regions
Kaushik Mitra, C. J. Williams, C. A. R. Sa de Melo
Atomic or molecular bosons in harmonically confined optical lattices exhibit a wedding cake structure consisting of insulating (Mott) shells. It is shown that superfluid regions em…
