Business card Dr. Régis Decker

Experimental condensed-matter physicist investigating the electronic structure and elementary excitations in novel quantum materials and low-dimensional systems, such as transition-metal and rare-earth compounds, magnetic materials, superconductors, and van der Waals materials. My research combines advanced synchrotron-based spectroscopies, including high-resolution resonant inelastic X-ray scattering (RIXS), high-efficiency transition-edge-sensor (TES)-based X-ray emission spectroscopy (XES), and angle-resolved photoemission spectroscopy (ARPES), complemented by scanning tunneling microscopy (STM). A central aspect of my work is the development and scientific exploitation of state-of-the-art soft-X-ray spectroscopy instrumentation at BESSY II enabling high-resolution and impurity-level spectroscopy of quantum materials. In parallel to my research I teach data analysis and data management at the TU Berlin.
