Decay of a superfluid currents in a moving system of strongly interacting bosons
A. Polkovnikov, E. Altman, E. Demler +2
We analyze the stability and decay of supercurrents of strongly interacting bosons on optical lattices. At the mean field level, the system undergoes an irreversible dynamic phase…
Nonlinear optics with stationary pulses of light
A. Andre, M. Bajcsy, A. S. Zibrov +1
We show that the recently demonstrated technique for generating stationary pulses of light [Nature {\bf 426}, 638 (2003)] can be extended to localize optical pulses in all three sp…
Engineering Superfluidity in Bose-Fermi Mixtures of Ultracold Atoms
D. -W. Wang, M. D. Lukin, E. Demler
We investigate many-body phase diagrams of atomic boson-fermion mixtures loaded in the two-dimensional optical lattice. Bosons mediate an attractive, finite-range interaction betwe…
Quantum information processing using localized ensembles of nuclear spins
J. M. Taylor, G. Giedke, H. Christ +5
We describe a technique for quantum information processing based on localized en sembles of nuclear spins. A qubit is identified as the presence or absence of a collective excitati…
Shaping quantum pulses of light via coherent atomic memory
M. D. Eisaman, L. Childress, A. Andre +3
We describe a technique for generating pulses of light with controllable photon numbers, propagation direction, timing, and pulse shapes. The technique is based on preparation of a…
Fractional quantum Hall states of atoms in optical Lattices
Anders S. Sorensen, Eugene Demler, Mikhail D. Lukin
We describe a method to create fractional quantum Hall states of atoms confined in optical lattices. We show that the dynamics of the atoms in the lattice is analogous to the motio…
