Journal ArticleDOI
Calibration of a single-atom detector for atomic microchips
Alexander Stibor,S. Kraft,T. Campey,D. Komma,Andreas Günther,József Fortágh,Chris J. Vale,Halina Rubinsztein-Dunlop,Claus Zimmermann +8 more
TL;DR: In this paper, the authors used photoionization of atoms and subsequent detection of the generated ions. But they focused on the characterization of the ion detector with emphasis on its calibration via the correlation of ions with simultaneously generated electrons and achieved a detection efficiency of 47.8±2.6 %.
Journal ArticleDOI
First and second sound of a unitary Fermi gas in highly oblate harmonic traps
TL;DR: In this article, the first and second sound modes of a unitary Fermi gas trapped in a highly oblate harmonic trap at finite temperatures were theoretically investigated, and two possible schemes, sound wave propagation and breathing mode excitation, were considered.
Journal ArticleDOI
Dimensional crossover in a strongly interacting ultracold atomic Fermi gas
TL;DR: In this paper, the location of the maximum critical velocity in the quasi-two-dimensional regime behaves differently from its two-and three-dimensional asymptotic scalings, and this behavior may be experimentally probed using Bragg spectroscopy.
Journal ArticleDOI
Dynamical tunneling with ultracold atoms in magnetic microtraps
Martin Lenz,Sebastian Wüster,Chris J. Vale,Norman R. Heckenberg,Halina Rubinsztein-Dunlop,C. A. Holmes,Gerard J. Milburn,Matthew J. Davis +7 more
TL;DR: In this paper, the authors consider dynamical tunneling with ultracold atoms in magnetic microtraps on atom chips and find the Floquet spectrum for one of these as a function of the potential strength, modulation, and effective Planck's constant.
Journal ArticleDOI
Atom counting in ultracold gases using photoionization and ion detection
T. Campey,Chris J. Vale,Matthew J. Davis,Norman R. Heckenberg,Halina Rubinsztein-Dunlop,S. Kraft,Claus Zimmermann,József Fortágh +7 more
TL;DR: In this paper, the realization of Bose-Einstein condensation BEC in atom optics is described, with coherence lengths of less than 1 m, which is the shortest known coherence length for a single atom.
