Condensed Matter Dynamics Department
Director: Prof. Dr. Andrea Cavalleri
The Condensed Matter Department investigates the dynamics of solids using time dependent techniques. Tabletop and accelerator-based light sources, covering the whole electromagnetic spectrum from the THz to the hard X-rays, measure the structural dynamics of electrons, spins and atomic lattices in quantum condensed matter.
Several independent research groups are exploring alternative techniques, including attosecond timescale X-ray spectroscopies of solids, quasiparticle dynamics on the femtosecond time scale and computational nanoscale imaging.
The Condensed Matter Dynamics group is led by Prof. Andrea Cavalleri
and focuses on non-equilibrium phenomena in solids. Especially, we investigate how electronic and structural order can emerge as a result external drives, how transitions occur in solids dynamically and how energy flows into and away from a solid ... [more]
group focuses on quasiparticle dynamics on the femtosecond time scale. Our technique of choice is time- and angle-resolved photoemission spectroscopy in combination with selected electronic and vibrational excitation schemes as well as in situ sample preparation and low-energy electron diffraction ...

The guest research group of Guido Meier
investigates the influence of lateral nanostructuring and of coupling effects of ferromagnetic nanostructures with experimental methods and with micromagnetic simulations. Magnetism in micro- and nanostructured elements is of fundamental scientific interest, but has also the potential for applications, for example in spin electronic devices, memory applications, and in the medical sector ...

The group led by Kartik Ayyer
will focus on developing new methods to image nanoscale objects such as biomolecules, primarily using X-rays. We will develop new image reconstruction algorithms and apply them to experimental data with the scientific goal of determining their structure as well as understanding their dynamics. [more]
The group of Sebastian Loth
studies dynamical processes in nanostructures. Of particular interest is the question how quantum confinement and enhanced electron-electron interaction modify the time-dependent evolution of low-energy excitations in nanomagnets, molecules and charge-ordered surfaces ... [more]
The group of Adrian L. Cavalieri
investigates ultrafast dynamics occurring in atomic, molecular and solid-state systems. Of particular interest are optically driven electronic dynamics in materials, which may occur on the attosecond timescale and can directly precede comparatively slower, femtosecond structural dynamics and bulk phase transitions ...
