Strongly Correlated 2D Quantum Phases with Cold Polar Molecules: Controlling the Shape of the Interaction Potential
(American Physical Society (APS), 2007)
We discuss techniques to tune and shape the long-range part of the interaction potentials in quantum gases of polar molecules by dressing rotational excitations with static and microwave fields. This provides a novel tool ...
Decoherence Dynamics in Low-Dimensional Cold Atom Interferometers
(American Physical Society (APS), 2007)
We report on a study of the dynamics of decoherence of a matter-wave interferometer, consisting of a pair of low-dimensional cold atom condensates at finite temperature. We identify two distinct regimes in the time dependence ...
Preparation and Detection of Magnetic Quantum Phases in Optical Superlattices
(American Physical Society (APS), 2007)
We describe a novel approach to prepare, detect, and characterize magnetic quantum phases in ultracold spinor atoms loaded in optical superlattices. Our technique makes use of singlet-triplet spin manipulations in an array ...
Spectroscopy of Collective Excitations in Interacting Low-Dimensional Many-Body Systems Using Quench Dynamics
(American Physical Society (APS), 2007)
We study the problem of rapid change of the interaction parameter (quench) in a many-body lowdimensional system. It is shown that, measuring the correlation functions after the quench, the information about a spectrum of ...
Fractional quantum Hall effect in optical lattices
(American Physical Society (APS), 2007)
We analyze a recently proposed method to create fractional quantum Hall FQH states of atoms confined in optical lattices A. Sørensen et al., Phys. Rev. Lett. 94, 086803 2005 . Extending the previous work, we investigate ...
