Welcome to the CRC 1242
Non-Equilibrium Dynamics of Condensed Matter in the Time Domain
Non-equilibrium states can be created in condensed matter through ultrashort pulsed external stimuli such as light, pressure, electrical voltage, or particles. This Collaborative Research Centre aims to achieve a material-specific, microscopic understanding of such non-equilibrium states. To this end, new tools in experimental and theoretical physics will be developed to describe the time evolution from the moment of the stimulus to a state close to equilibrium in time and space.

Au(111) surface captured with a low energy electron microscope. On the Gold surface, small "hills" were seen that look like spring flowers in false colors.

Layout of the recently built SFG spectrometer. This should enable the measurements of molecular level structures and femtosecond dynamics at various interfaces.

Electron density redistribution in a Fe/(MgO)3 (001) heterostructure upon a fs-laser excitation with a photon energy of 7.75 eV after 20 fs, simulated using real-time time-dependent DFT.

"Dance around Center Spot" - STM image of an ordered surface alloy of Gold and Silver atoms on Si(111) creating a sill unresolved reconstruction.

Graphene-based THz detector: the logarithmic-periodic antenna couples the THz radiation to a micrometer-sized graphene flake that is in the center of the antenna. The antenna with a diameter of 1 mm is patterned by electron-beam lithography, the substrate is semi-intrinsic SiC.

View into a UHV chamber used for pulsed laser deposition. An invisible 248 nm laser is hitting a rotating SrTiO3 target, causing heated material to be ejected with a visible, bluish plasma plume, used to deposit thin films onto a heated substrate. The red hot surface of the substrate heater at 700°C is visible in the center, reflected on the back of the open shutter.

On a hot spoon, a drop of water takes on an unusual shape. This analogy experiment of the Ö project shows how matter can assume unusual dynamic states when it is far from equilibrium. The causal reason for the unusual water star lies in the Leidenfrost effect.
