After twelve successful years SFB TRR 21 CO.CO.MAT has terminated on 30 June 2017. We would like to thank all of our members, supporters, collaborators and DFG who have contributed to this success over the years.


Quantum matter offers a spectacular variety of physical phenomena like superfluidity, superconductivity and anomalous transport in low-dimensional electron systems. On the other hand, our understanding of the physical properties of nanoscopic and mesoscopic quantum matter and quantum devices is limited. This is mostly due to the fact that these properties are governed by strong correlations and quantum effects. Therefore, systems that provide well defined geometries and dynamic control parameters are well suited to grant new insights on
  1. how to find new states of matter,
  2. how to tailor new dynamic cooperative quantum states,
  3. how to understand the scaling behaviour of their properties from few body to many body physics,
  4. how to probe and influence the effects of decoherence and
  5. how to control light matter states.

Over the last years, one has made rapid progress in the ability to control quantum gases as interacting quantum matter in well defined geometries at ultralow temperatures. On the other hand, mesoscopic systems and devices show in many respects very similar behaviour. Therefore it was our goal to unify the common physics arising in mesoscopic systems and quantum gases to improve our understanding of quantum matter and exploit these abilities to discover new phenomena.
