Symmetric micro-wave potentials for interferometry with thermal atoms on a chip
M. Ammar, M. Dupont-Nivet, L. Huet +8
A trapped atom interferometer involving state-selective adiabatic potentials with two microwave frequencies on a chip is proposed. We show that this configuration provides a way to…
Interaction-induced crossover versus finite-size condensation in a weakly interacting trapped one-dimensional Bose gas
Isabelle Bouchoule, Karen V. Kheruntsyan, Gora Shlyapnikov
We discuss the transition from a fully decoherent to a (quasi-)condensate regime in a harmonically trapped weakly interacting 1D Bose gas. By using analytic approaches and verifyin…
Realizing a stable magnetic double-well potential on an atom chip
Jerome Esteve, Thorsten Schumm, Jean-Baptiste Trebbia +3
We discuss design considerations and the realization of a magnetic double-well potential on an atom chip using current-carrying wires. Stability requirements for the trapping poten…
Modulational instabilities in Josephson oscillations of elongated coupled condensates
Isabelle Bouchoule
We study the Josephson oscillations of two coupled elongated condensates. Linearized calculations show that the oscillating mode uniform over the length of the condensates (uniform…
The role of wire imperfections in micro magnetic traps for atoms
Jerome Esteve, Christine Aussibal, Thorsten Schumm +5
We present a quantitative study of roughness in the magnitude of the magnetic fieldproduced by a current carrying microwire, i.e. in the trapping potential for paramagnetic atoms.W…
