Welcome to the Palaiseau Theoretical Spectroscopy Group
The Theoretical Spectroscopy Group at the Laboratoire des Solides Irradiés develops fundamental condensed matter theory in close contact with experiment and applications. Since 2000, when the research profile of the group has been defined, electronic excitations are at the centre of our interest. The theoretical framework covers static and time-dependent Density Functional Theory, and Many-Body Perturbation Theory. We develop theory and ab initio computer codes, and we work on applications ranging from atoms to molecules, nanostructures, solids and liquids, from metals to insulators.
