Lifshitz-like transition and enhancement of correlations in a rotating bosonic ring lattice
Ana Maria Rey, Keith Burnett, Indubala I. Satija +1
We study the effects of rotation on one-dimensional ultra-cold bosons confined to a ring lattice. For commensurate systems, at a critical value of the rotation frequency, an infini…
Adiabatic Phase Diagram of an Ultracold Atomic Fermi Gas with a Feshbach Resonance
S. Watabe, T. Nikuni, N. Nygaard +2
We determine the adiabatic phase diagram of a resonantly-coupled system of Fermi atoms and Bose molecules confined in the harmonic trap by using the local density approximation. Th…
Adiabatic Phase Diagram on Degenerate Fermi Gas with Feshbach-Resonance
S. Watabe, T. Nikuni, N. Nygaard +2
We determine the adiabatic phase diagrams for a resonantly-coupled system of Fermi atoms and Bose molecules confined in a harmonic trap by using the local density approximation. Th…
Metal-Insulator Transition Revisited for Cold Atoms in Non-Abelian Gauge Potentials
Indubala I. Satija, Daniel C. Dakin, Charles W. Clark
We discuss the possibility of realizing metal-insulator transitions with ultracold atoms in two-dimensional optical lattices in the presence of artificial gauge potentials. Such tr…
Hanbury Brown-Twiss Interferometry for Fractional and Integer Mott Phases
Ana Maria Rey, Indubala I. Satija, Charles W. Clark
Hanbury-Brown-Twiss interferometry (HBTI) is used to study integer and fractionally filled Mott Insulator (MI) phases in period-2 optical superlattices. In contrast to the quasimom…
Quantum coherence of Hard-Core-Bosons and Fermions : Extended, Glassy and Mott Phases
Ana Maria Rey, Indubala I. Satija, Charles W. Clark
We use Hanbury-Brown-Twiss interferometry (HBTI) to study various quantum phases of hard core bosons (HCBs) and ideal fermions confined in a one-dimensional quasi-periodic (QP) pot…
