Novel measurement tools for many-body experiments

As experimental quantum-optical architectures permit the realization of novel states of matter, novel tools become necessary to actually observe these. In this respect, quantum-optics setups offer completely new possibilities, for example through the ability to manipulate individual particles and to track their dynamical evolution in real time. Exploiting these abilities, we design novel tools for observing and characterizing quantum mechanical states of matter in quantum-optical setups.
