Dipolar Bosons in Triangular Optical Lattices: Quantum Phase Transitions and Anomalous Hysteresis
Daisuke Yamamoto, Ippei Danshita, Carlos A. R. Sá de Melo
We study phase transitions and hysteresis in a system of dipolar bosons loaded into triangular optical lattices at zero temperature. We find that the quantum melting transition fro…
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…
Vortex-Antivortex Lattice in Ultra-Cold Fermi Gases
S. S. Botelho, C. A. R. Sa de Melo
We discuss ultra-cold Fermi gases in two dimensions, which could be realized in a strongly confining one-dimensional optical lattice. We obtain the temperature versus effective int…
