We have open PhD and Postdoc positions supported by ERC advanced grant.

 

We have directly observed a Feshbach-resonance by Coincidence-detection of Ions and Electrons in Penning Ionization Collisions. 

 

 

We present a new experimental approach for observing molecular dynamics involving neutral particles and ions that is capable in providing state-to-state mapping of the dynamics.

In a joint theory and experiment investigation we show that phase plays a major role in protecting a decaying quantum state, a phenomenon that leads to orders of magnitude increase in lifetime.
