LPMS - Laboratory of Physics of Materials and Surfaces

LPMS is an experimental physics laboratory of condensed matter and surface science. It is specialized in the study of electronic properties of solids, magnetism and light-matter interaction by spectroscopic techniques based on laser and synchrotron radiation sources, and in particular spin-, time- and angle-resolved photoemission spectroscopy (STAR-PES). LPMS is associated to the DICO group of LIDYL at CEA Saclay.
