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…
Twin matter waves for interferometry beyond the classical limit
Bernd Lücke, Manuel Scherer, Jens Kruse +10
Interferometers with atomic ensembles constitute an integral part of modern precision metrology. However, these interferometers are fundamentally restricted by the shot noise limit…
Spontaneous breaking of spatial and spin symmetry in spinor condensates
M. Scherer, B. Lücke, G. Gebreyesus +6
Parametric amplification of quantum fluctuations constitutes a fundamental mechanism for spontaneous symmetry breaking. In our experiments, a spinor condensate acts as a parametric…
Influence of the particle number on the spin dynamics of ultracold atoms
Jannes Heinze, Frank Deuretzbacher, Daniela Pfannkuche
We study the dependency of the quantum spin dynamics on the particle number in a system of ultracold spin-1 atoms within the single-spatial-mode approximation. We find, for all str…
