"First, the sample was excited with an infrared pulse and then measured with high time resolution using angle-resolved photoemission spectroscopy (tr-ARPES). "For the first time, we were able to observe and characterize all phases of excitation, thermalization and relaxation on ultrashort time scales," says Sánchez-Barriga. The most important result: "The data show that the thermal equilibrium between the system of electrons and the crystal lattice is restored"
