Light-matter interaction with electron nanoemitters
We investigate the fundamental properties of ultrafast interactions of light and matter on the nanometer scale. In order to do so, we focus extremely short laser pulses on sharp metal tips.

Already for decades electrons can be trapped in Penning traps, resembling bottles for electrons that mainly rely on a strong magnetic field. Paul traps consist of an alternating electric field, and much more complex trap geometries are possible, for example beam splitters. We have, for the first time, set up a planar Paul trap for electrons in order to do experiments with novel interferometers. Also the controlled interaction of charged particles amongst themselves or with other quantum objects may be investigated.
Electron acceleration with laser light
In this experiment we aim at showing that it is possible to accelerate and steer electrons right with the electric field of a laser pulses.
