Magnetization Plateaus for Spin-One Bosons in Optical Lattices: Stern-Gerlach Experiments with Strongly Correlated Atoms
(American Physical Society (APS), 2004)
We consider insulating states of spin-one bosons in optical lattices in the presence of a weak magnetic field. For the states with more than one atom per lattice site we find a series of quantum phase transitions between ...
Probing many-body states of ultracold atoms via noise correlations
(American Physical Society (APS), 2004)
We propose to utilize density-density correlations in the image of an expanding gas cloud to probe complex many-body states of trapped ultracold atoms. In particular, we show how this technique can be used to detect ...
Disordered Bose-Einstein Condensates in Quasi-One-Dimensional Magnetic Microtraps
(American Physical Society (APS), 2004)
We analyze the effects of a random magnetic potential in a microfabricated waveguide for ultracold atoms. We find that the shape and position fluctuations of a current carrying wire induce a strong Gaussian correlated ...
Luttinger Liquid of Polarons in One-Dimensional Boson-Fermion Mixtures
(American Physical Society (APS), 2004)
We use the bosonization approach to investigate quantum phases of boson-fermion mixtures (BFM) of atoms confined to one dimension by an anisotropic optical lattice. For a BFM with a single species of fermions we find a ...
