The granularity of weakly occupied bosonic fields beyond the local density approximation
M. Eckart, R. Walser, W. P. Schleich +2
We examine ground state correlations for repulsive, quasi one-dimensional bosons in a harmonic trap. In particular, we focus on the few particle limit N=2,3,4,..., where exact nume…

Dropping cold quantum gases on Earth over long times and large distances
G. Nandi, R. Walser, E. Kajari +1
We describe the non-relativistic time evolution of an ultra-cold degenerate quantum gas (bosons/fermions) falling in Earth's gravity during long times (10 sec) and over large dista…

Evolution of a spinor condensate: coherent dynamics, dephasing and revivals
J. Kronjäger, C. Becker, M. Brinkmann +4
We present measurements and a theoretical model for the interplay of spin dependent interactions and external magnetic fields in atomic spinor condensates. We highlight general fea…
