Matter waves in fundamental and applied physics

Matter waves and their interference provide sensitive probes for a broad range of important physics. On the fundamental side, it is possible to search for new physics in outstandingly precise experiments - such as candidates for dark matter and dark energy, violations of Lorentz invariance and the equivalence principle, or minuscule deviations from the Standard Model. On the applied side, we measure inertial forces and gravity, develop instruments for the life sciences, and may help to define SI units. Applying methods from atomic, molecular, and optical physics, we advance experimental technology to push the sensitivity of experiments to new levels. 

We are deeply grateful for the funding agencies who provide us the means to pursue our work.
