Abstract

Interactions among electrons and phonons, excitons and phonons, as well as between phonons themselves, play a crucial role in determining many technologically relevant material properties. These interactions significantly influence superconductivity, electrical and thermal transport, excitonic phenomena, polaron formation, and indirect optical absorption. This colloquium highlights both fundamental and computational research based on density functional theory for modeling strongly correlated systems in bulk and two-dimensional materials. Achieving a deeper understanding of these quasiparticles requires strengthened collaboration between theoretical and experimental research communities. A particular emphasis will be placed on integrating computational approaches into ongoing studies of strongly correlated electron systems. We will discuss general applications of scattering techniques using neutrons and photons, and how such approaches complement theoretical and computational studies of materials. Finally, we will provide an overview of the European Spallation Source (ESS) and its capabilities as a world-class neutron and light source facility, highlighting how these experimental tools can support research in material science and condensed matter physics. The program will include invited talks and oral presentations.
