KurzbeschreibungThis course provides an overview of experimental methods and techniques used to study dynamical processes in solids. Many processes in solids happen on a picosecond to femtosecond time scale. In this course we discuss different methods to generate femtosecond photon pulses and measurement techniques adapted to time resolved experiments.
LernzielThe goal of the course is to enable students to identify and evaluate experimental methods to manipulate and measure the electronic, magnetic and structural properties of solids on the fastest possible time scales. These "ultrafast methods" potentially lead both to an improved understanding of fundamental interactions in condensed matter and to applications in data storage, materials processing and solid-state computing.
