Loth Group

We are an innovative research group exploring physics at the atomic scale. We are part of the Institute for Functional Matter and Quantum Technologies at the University of Stuttgart. 

We design experiments that can interact with matter on its fundamental length scale of individual atoms. We create functional nanostructures atom by atom and use them to test physical limits of miniaturization and study the emergence of quantum behavior in magnetic nanostructures and correlated-electron materials. Of particular interest is the question how quantum confinement, exchange coupling between atoms and enhanced electron-electron interaction modify the time-dependent evolution of low-energy excitations in nanomagnets, molecules and charge-ordered surfaces.

For this purpose we combine scanning tunneling microscopy and ultrafast pump-probe spectroscopy to push the boundaries of time resolution in scanning probe microscopy. The novel instruments developed by us are ideally matched to the energetic, spatial and temporal scales relevant to correlated electron and spin dynamics. 

It is our goal to uncover the intriguing phenomena that govern physics at the atomic scale.
