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).

Condensed Matter

When atoms interact things can get interesting. Fundamental research on the underlying properties of materials and nanostructures and exploration of the potential they provide for applications.
