Lay Summary (English)

Lay summary
Strongly correlated electron systems remain among the most active, diverse and challenging research topics of modern condensed matter physics. The present project is mainly devoted to unconventional superconductivity and the transport properties in artificially structured transition metal oxides.Among the unconventional superconductors the non-centrosymmetric and the chiral spin triplet superconductors have been in the focus of our study. The former is interesting due to novel properties of the superconducting phase induced by the unusual electronic spin structure leading to a new form of Cooper pairing. In the latter case new proposal for test the structure of the superconducting phase, especially its chirality, have been put forward in view of the question of the Cooper pairing symmetry in Sr2RuO4. In the context of spintronics the control of Josephson spin currents between spin triplet superconductors through magnetic tunneling barriers has been investigated. The possibility of producing atomically precise heterostructures of different strongly correlated electron systems prompted us to develop theoretical methods for their treatment. Especially magnetic and transport properties are at the center of our interest. This includes especially thermopower which of interest in view of applications and the potential of such structures to yield new types of designable functional materials.
