We collaborate within the SFB 306 on quantum cooperativity effects usinge cold crystals of trapped ions.
In one project A1 we focus on the coopartivity when observing scattered light from ion crystals. A review of the theoretical foundations and the experimental status is:

In the other project B1 we study the quantum cooperatitivity induced by the coupling of ions to the common modes of vibration. Recent publications are:
