The neutron-scattering group investigates the structure and dynamics of solids by means of elastic or inelastic neutron scattering. In addition, hard x-ray scattering measurements (elastic and inelastic) are carried out as well. Other experimental techniques, e.g. photoemission spectroscopy, are performed at large-scale user facilities when it is deemed necessary. The scientific focus is on lattice dynamical properties of solids, the interaction of the lattice with magnetic and electronic degrees of freedom and its evolution with extrinsic parameters such as chemical composition, pressure or temperature. We profit from close cooperation with the Theory of Quantum Materials department for ab-initio lattice dynamical calculations and the New Quantum Materials department for sample growth and characterization. Currently, we are particularly interested in phonon-mediated and iron-based superconductors, the physics of transition-metal monosilicides and charge-ordered materials. Until recently, we operated a thermal neutron triple-axis spectrometer at the (now closed) research reactor ORPHEE at CEA Saclay. Nonetheless, we were and are frequent guests at neutron and synchrotron user facilities around the world and will continue to be so.
