Research Topics

  • Angle-Resolved Photoemission Spectroscopy
  • Synchrotron Studies of Quantum Matter

In order to understand, predict and control the physical properties of a material, it is necessary to know its electronic and crystal structures. This knowledge can be gained from the interaction of the matter with radiation. The most efficient way to produce focused radiation of various wavelengths, small bandwidth and high intensity is realized at the large-scale facilities, the so-called synchrotron light sources. We study the microscopic behaviour of electrons and characterize static and dynamic properties of complex electron systems by means of state-of-the-art photoemission and x-ray scattering techniques. We focus on two types of synchrotron-based experiments, namely (i) photoemission spectroscopy (most notably angle-resolved) and (ii) x-ray scattering (elastic and inelastic). These experiments enable to study the electronic structure, elementary excitations, and static ordering of interacting electrons. By combining these two types of experiments we aim at establishing a comprehensive understanding of complex electron systems and their behaviour on various energy, time, and length scales. Angle-resolved photoemission spectroscopy (ARPES) is a powerful tool to determine the low-energy electron dynamics in solids. We typically use the synchrotron radiation with the energies in the range of 6-300 eV to record the energy and momentum distribution of the photoelectrons which leave the surface of the sample. This distribution is then used to extract the spectral function – the probability to find the electron with given energy and momentum in the single-crystal, i.e. its electronic structure. Modern x-ray scattering experiments allow to investigate the elementary excitations and the static order of complex electron systems in great detail. For instance, resonant inelastic x-ray scattering (RIXS) is a new powerful tool to study spin, orbital and charge excitations in an element specific way. Similarly, resonant elastic x-ray scattering (REXS) allows to observe the "crystallization" of interacting electrons in an element specific way; i.e., to investigate the static ordering spins, orbitals and charges. Materials hosting complex electron systems are a treasure trove for fascinating physical properties that raise great expectations for technological applications. Very prominent examples are unconventional superconductors, topological insulators, electronic density waves, multiferroics or heavy fermion systems. These materials are in the focus of many other IFF activities. The Group is thus organically embedded in the structure of the institute. We are involved in numerous internal research projects and can also provide a characterization service to other groups. External collaborations of the group constitute the powerful worldwide network with the participation of leading research institutions.
