Many Particle Phenomena

Prof. Wilhelm Zwerger

Research Field

Ultracold Atoms

Cold atoms provide idealized and widely tunable model systems for the study of many-body phenomena and strong correlations. Their interaction strength is adjustable either directly by Feshbach resonances, where the scattering length is resonantly enhanced or, effectively, in optical lattices, where atoms are trapped in artificial crystals due to light forces. Current topics of research in this area are fermionic gases near the limit of infinite scattering length, in particular transport in the absence of quasiparticles, and topological phases of interacting atoms in optical lattices.

Condensed Matter

Optical properties provide a valuable tool to probe elemtary excitations near quantum critical points. In particular, we study Magnon-Magnon interactions and possible signatures of a Higgs-Mode in Raman measurements on high temperature superconductors which were performed in the group of R. Hackl (WMI).
