Free fermion antibunching in a degenerate atomic Fermi gas released from an optical lattice
T. Rom, Th. Best, D. van Oosten +4
Noise in a quantum system is fundamentally governed by the statistics and the many-body state of the underlying particles. Whereas for bosonic particles the correlated noise observ…
Direct Observation of Second Order Atom Tunnelling
S. Foelling, S. Trotzky, P. Cheinet +5
Tunnelling of material particles through a classically impenetrable barrier constitutes one of the hallmark effects of quantum physics. When interactions between the particles comp…
Expansion of a quantum gas released from an optical lattice
F. Gerbier, S. Trotzky, S. Foelling +9
We analyze the interference pattern produced by ultracold atoms released from an optical lattice. Such interference patterns are commonly interpreted as the momentum distributions…
Preparation and detection of d-wave superfluidity in two-dimensional optical superlattices
A. M. Rey, R. Sensarma, S. Foelling +3
We propose a controlled method to create and detect d-wave superfluidity with ultracold fermionic atoms loaded in two-dimensional optical superlattices. Our scheme consists in prep…
Adiabatic loading of a Bose-Einstein condensate in a 3D optical lattice
T. Gericke, F. Gerbier, A. Widera +3
We experimentally investigate the adiabatic loading of a Bose-Einstein condensate into an optical lattice potential. The generation of excitations during the ramp is detected by a…
Hybrid 2D surface trap for quantum simulation
J. I. Gillen, W. S. Bakr, A. Peng +3
We demonstrate a novel optical trapping scheme for ultracold atoms. Using a combination of evanescent wave, standing wave, and magnetic potentials we create a deeply 2D Bose-Einste…
Counting atoms using interaction blockade in an optical superlattice
P. Cheinet, S. Trotzky, M. Feld +4
We report on the observation of an interaction blockade effect for ultracold atoms in optical lattices, analogous to Coulomb blockade observed in mesoscopic solid state systems. Wh…
