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),…
Superfluid and Fermi liquid phases of Bose-Fermi mixtures in optical lattices
Kaushik Mitra, C. J. Williams, C. A. R. Sá de Melo
We describe interacting mixtures of ultracold bosonic and fermionic atoms in harmonically confined optical lattices. For a suitable choice of parameters we study the emergence of s…
Superfluid and Mott Insulating shells of bosons in harmonically confined optical lattices
Kaushik Mitra, C. J. Williams, C. A. R. Sa de Melo
Weakly interacting atomic or molecular bosons in quantum degenerate regime and trapped in harmonically confined optical lattices, exhibit a wedding cake structure consisting of ins…
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…
