Pump-Probe Photoelectron Spectra

Pump-probe photoelectron spectroscopy provides a tool to observe excitations taking place in electronic systems as they evolve in time. This technique is frequently applied to study complex phenomena taking place in chemistry and solid-state physics. To properly capture the dynamics observed in the experiments, one needs to employ non-perturbative theories capable to describe the complete time evolution of large physical systems. After a pedagogical survey on the literature, in this chapter, we focus on TDDFT and illustrate how this theory can be formulated in a way that can capture the entire ionization dynamics in atoms, molecules, and solids.
