Sub-atom shot noise Faraday imaging of ultracold atom clouds
Mick A. Kristensen, Miroslav Gajdacz, Poul L. Pedersen +4
We demonstrate that a dispersive imaging technique based on the Faraday effect can measure the atom number in a large, ultracold atom cloud with a precision below the atom shot noi…
Preparation of ultracold atom clouds at the shot noise level
Miroslav Gajdacz, Andrew J. Hilliard, Mick A. Kristensen +4
We prepare number stabilized ultracold clouds through the real-time analysis of non-destructive images and the application of feedback. In our experiments, the atom number ${N\sim1…
Spin dynamics in a two dimensional quantum gas
Poul L. Pedersen, Miroslav Gajdacz, Frank Deuretzbacher +5
We have investigated spin dynamics in a 2D quantum gas. Through spin-changing collisions, two clouds with opposite spin orientations are spontaneously created in a Bose-Einstein co…
Production and manipulation of wave packets from ultracold atoms in an optical lattice
Poul L. Pedersen, Miroslav Gajdacz, Nils Winter +3
Within the combined potential of an optical lattice and a harmonic magnetic trap, it is possible to form matter wave packets by intensity modulation of the lattice. An analysis of…
Non-destructive Faraday imaging of dynamically controlled ultracold atoms
Miroslav Gajdacz, Poul L. Pedersen, Troels Mørch +3
We describe an easily implementable method for non-destructive measurements of ultracold atomic clouds based on dark field imaging of spatially resolved Faraday rotation. The signa…
Pump-probe coupling of matter wave packets to remote lattice states
Jacob F. Sherson, Sung Jong Park, Poul Pedersen +4
The coherent manipulation of wave packets is an important tool in many areas of physics. We demonstrate the experimental realization of quasi-free wave packets of ultra-cold atoms…
