Dynamics of parametric matter wave amplification
Robert Bücker, Ulrich Hohenester, Tarik Berrada +7
We develop a model for parametric amplification, based on a density matrix approach, which naturally accounts for the peculiarities arising for matter waves: significant depletion…
Hanbury Brown and Twiss correlations across the Bose-Einstein condensation threshold
Aurélien Perrin, Robert Bücker, Stephanie manz +5
Hanbury Brown and Twiss (HBT) correlations, i.e. correlations in far-field intensity fluctuations, yield fundamental information on the quantum statistics of light sources, as high…
Twin-atom beams
Robert Bücker, Julian Grond, Stephanie Manz +7
We present highly efficient emission of twin-atom beams into a single transversal mode of a waveguide potential. The source is a one-dimensional degenerate Bose gas in the first ra…
Two-point phase correlations of a one-dimensional bosonic Josephson junction
Thomas Betz, Stephanie Manz, Robert Bücker +8
We realize a one-dimensional Josephson junction using quantum degenerate Bose gases in a tunable double well potential on an atom chip. Matter wave interferometry gives direct acce…
Two-point density correlations of quasicondensates in free expansion
S. Manz, R. Bücker, T. Betz +8
We measure the two-point density correlation function of freely expanding quasicondensates in the weakly interacting quasi-one-dimensional (1D) regime. While initially suppressed i…
Density ripples in expanding low-dimensional gases as a probe of correlations
A. Imambekov, I. E. Mazets, D. S. Petrov +6
We investigate theoretically the evolution of the two-point density correlation function of a low-dimensional ultracold Bose gas after release from a tight transverse confinement.…
