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...

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...

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...

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...
