Our fields of investigation ...

We investigate very different material systems, from single magnetic molecules to spin chains, thin films and multilayers to three-dimensional metals.

It is characteristic that in all materials the interaction of the electrons with each other is decisive for the properties. These are many-particle quantum systems that cannot be understood with one-particle band models, as is the case with simple semiconductors, for example.  These systems show basic states such as superconductivity, ferro- and antiferromagnetism, spin fluids, charge and spin density waves, which can only be described within the framework of modern multi-particle quantum theory and offer new properties and functionalities.

High temperature copper and iron pnictide superconductors, rare earth metals with frustrated magnetic interactions, heavy fermion superconductors, one-dimensional quantum spin chains, molecular magnets, and much more are investigated.
