    The Bose Hubbard model (BHM) is a minimal model that describes interacting ultracold bosons in an optical lattice, allowing the opportunity for experiments to probe quench dynamics of the model. Theoretically, it has proven challenging to study spatio-temporal correlations in the BHM in dimensions higher than one. We use the Schwinger-Keldysh technique and a strong-coupling expansion to...

  2. 986. Nonclassical diffusion in a nondegenerate ultracold gas

    Invited Speaker / Conférencier invité
    We study the crossover from classical to quantum diffusion by studying the equilibration of longitudinal spin domains in a trapped 87Rb sample just above quantum degeneracy. By controlling the degree of spin coherence in the domain wall, we can dramatically alter the relaxation dynamics of the system. Coherence in the domain wall leads to transverse-spin-mediated longitudinal spin diffusion...

  3. 1201. Calibration of a Larmor Clock for Tunneling Time Experiments
    Mr David Spierings (University of Toronto)

    Division of Atomic, Molecular and Optical Physics, Canada / Division de la physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)
    Oral (Student, Not in Competition) / Orale (Étudiant(e), pas dans la compétition)
    How much time does it take for a particle to tunnel? This has been a controversial question for nearly a century because of the inability to make a direct measurement of time. One operational definition for the tunnelling time is the Larmor clock, in which the spin degree of freedom of a tunneling particle is used as a clock that ticks only inside the forbidden region due to the presence of a...

  4. 1237. Vortex formation in spin-orbit coupled Bose-Einstein condensates
    Lindsay LeBlanc (University of Alberta)

    Division of Atomic, Molecular and Optical Physics, Canada / Division de la physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)
    Oral (Non-Student) / orale (non-étudiant)
    Using techniques that exploit the high precision atomic physics, we have exquisite control over several degrees of freedom in an ultracold atomic system, with which we can create analogues to a broader class of physical systems through the principle of quantum simulation. Raman transitions give us the ability to effect a "spin-orbit coupling" in our ultracold gas, by facilitating the transfer...
