Theoretical Solid State Physics

The theory group of Nils Schopohl works on superconductivity and superfluidity based on the microscopic Dyson-Schwinger-Gorkov many body physics approach. Recent activities of the group govern applications of the microscopic theory to Josephson effects with nodal surfaces in high-temperature superconductors, the non linear Meissner effect, collective modes of dipolar BEC condensates, matter waves in wave-guides, highly excited alkali atoms, and a first principles theory of optical activity in crystals. There is a strong link between the experimental and theory groups with common seminars and research projects devoted to miscellaneous topics in superconductivity, cold atom research and quantum optics.
