Current research: Entanglement of atoms in microwave near-field potentials
I am currently working on an experiment employing a so called 'atom chip' which uses microfibricated wires on a substrate to coherently manipulate ultracold atoms. We use microwave near-fields on the atom chip to generate potentials which depend on the atomic internal state. With these state-dependent potentials we perform trapped-atom interferometry. Atomic collisions in the potential enable us to prepare spin-squeezed and many-particle entangled states. This technique is also very promising for the implementation of chip-based quantum gates.

Past research: Coherent slowing of ultrasonic atom beams
In 2005/06 I was working in Prof. M. G. Raizen's group at the University of Texas on a new way to slow a supersonic atom beam of ground state noble gas. For this, the beam is elastically reflected from a single-crystal mirror mounted on the tip of a spinning rotor. We were able to achieve a significant reduction in beam velocity while retaining the low beam temperature. For more information, please see my Master thesis.
