AbstractUltrafast 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.
ObjectiveAfter attending this course you understand 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.
Content1. Experimental techniques, an overview

2. Dynamics of the electron gas
2.1 First experiments on electron dynamics and lattice heating
2.2 The finite lifetime of excited states
2.3 Detection of lifetime effects
2.4 Dynamical properties of reactions and adsorbents

3. Dynamics of the lattice
3.1 Phonons
3.2 Non-thermal melting

4. Dynamics of the spin system
4.1 Laser induced ultrafast demagnetization
4.2 Ultrafast spin currents generated by lasers
4.3 Landau-Lifschitz-Dynamics
4.4 Laser induced switching

5. Correlated materials
Lecture noteswill be distributed
Literaturerelevant publications will be cited
Prerequisites / NoticeThe lecture can also be followed by interested non-physics students as basic concepts will be introduced.

This lecture is complementary to the lecture on "ultrafast methods for solid state physics" of the spring semester. Both lectures can be attended independently. The focus of this lecture is on the physical processes whereas the focus of the "ultrafast methods for solid state physics" lecture is on the experimental techniques.
