We have prepared samples of 1-10 fermionic atoms in a tightly confining
trap in which all quantum mechanical degrees of freedom can be controlled.
We thus have a generic model system that allows us to study few-body
theories developed for example in
nuclear physics with exceptional flexibility .
In first experiments we have studied a repulsively interacting two-particle
system and observed fermionization of two distinguishable fermions.
Furthermore we have studied pair tunneling out of an attractively
interacting system, revealing a strong odd-even effect.
In future experiments we plan to study thermalization of an isolated system,
as both microscopic as well as thermodynamic quantities can be evaluated for

Quantum flutter of supersonic particles in one-dimensional quantum liquids
We study the dynamics of an impurity injected at a supersonic velocity into
a 1D gas of hardcore bosons, or faster than the Fermi velocity in a fully
polarized Fermi gas. We find that at long times the momentum of the
impurity does not decay to zero, and demonstrate that the system exhibits a
new type of coherent oscillation in which the impurity vibrates with
respect to its correlation hole.
