Abstract

Ultrafast processes in solids are of fundamental interest as well as relevant for modern technological applications. The dynamics of the lattice, the electron gas as well as the spin system of a solid are discussed. The focus is on time resolved experiments which provide insight into pico- and femtosecond dynamics.

Objective

After attending this course you can analyze the dynamics of essential excitation processes which occur in solids and you have an overview over state of the art experimental techniques used to study fast processes. You will be able to evaluate experimental methods for ultra fast solid state physics.
