Reconfigurable self-sufficient traps for ultracold atoms based on a superconducting square
Reconfigurable self-sufficient traps ultracold atoms superconducting square Atomic Physics
2012/4/24
We report on the trapping of ultracold atoms in the magnetic field formed entirely by persistent supercurrents induced in a thin film type-II superconducting square. The supercurrents are carried by v...
Realization of an optomechanical interface between ultracold atoms and a membrane
optomechanical interface ultracold atoms membrane Quantum Gases

Abstract: We have realized a hybrid optomechanical system by coupling ultracold atoms to a micromechanical membrane. The atoms are trapped in an optical lattice, which is formed by retro-reflection of...
Theoretical description of two ultracold atoms in finite 3D optical lattices using realistic interatomic interaction potentials
Theoretical description two ultracold atoms finite 3D optical lattices realistic interatomic

Characterization of excited states ultracold atoms optical lattices
2011/9/15
Loading ultracold atoms in an optical lattice from a Bose-Einstein condensate is generally a nonadiabatic process resulting in the dynamical excitation of a wavepacket, a combination of several eigens...

We investigate theoretically the long-range electrostatic interactions between a ground-state homonuclear alkali-metal dimer and an excited alkali-metal atom taking into account its fine-structure. Th...
Resonantly Enhanced Tunneling and Transport of Ultracold Atoms on Tilted Optical Lattices
Tunneling Ultracold Atoms Tilted Optical Lattices
2011/9/9
We investigate the resonantly enhanced tunneling dynamics of ultracold bosons loaded on a tilted 1-D optical lattice, which can be used to simulate a chain of Ising spins and associated quantum phase ...
Ultracold Atoms as a Target: Absolute Scattering Cross-Section Measurements
Ultracold Atoms Target Scattering Cross-Section Measurements
2010/11/12
We report on a new experimental platform for the measurement of absolute scattering cross-sections. The target atoms are trapped in an optical dipole trap and are exposed to an incident particle beam...
We report a technique that uses clouds of ultracold atoms as sensitive, tunable, and non-invasive probes for microwave eld imaging with micrometer spatial resolution. The microwave magnetic eld comp...

The scattering amplitude ultracold atoms p-wave magnetic Feshbach Resonance
2010/11/9
Most of the current theories on the p-wave superfluid in cold atomic gases are based on the effective-range theory for the two-body scattering, where the low energy p-wave scattering amplitude $f_1(k)...

Simulation gauge transformations systems ultracold atoms
2010/10/21
We show that gauge transformations can be simulated on systems of ultracold atoms. We discuss observables that are invariant under these gauge transformations and compute them using a tensor network a...
