Electron-boson coupling in correlated materials: a non-equilibrium perspective — •Claudio Giannetti1, Stefano Dal Conte2, Giulio Cerullo2, and Andrea Damascelli3 — 1ILAMP, Università Cattolica del Sacro Cuore, via Musei 41, 25121 Brescia, Italy — 2Department of Physics, Politecnico di Milano, Piazza Leonardo da Vinci 32, 20133 Milano, Italy — 3Quantum Matter Institute, University of British Columbia, Vancouver, British Columbia V6T 1Z4, Canada
Non-equilibrium techniques are emerging as a unique tool to investigate the coupling of electrons to bosonic degrees of freedom in correlated materials. The recent advances in ultrafast science have paved the way to the study of electron-phonon and electron-spin interactions on their relevant timescales (10-100 fs).
In this talk we will provide an overview of the recent advances in the field and we will discuss the energy relaxation process in conventional anisotropic superconductors and in strongly-correlated materials, with particular focus on superconducting copper oxides.
