Lecture - Computer simulation of many body systems

Lecture:     Exercise:       Final-Kolloquium:

Thu 1:30 - 3:00 pm, P603

The Universe in the Computer

The lecture gives an overview on modern methods of theoretical physics for the investigation of many-body systems. Foundations and applications of computer simulations are in the focus, by which an approximation free and numerical exact analysis of complex systems from micro- to the macro-cosmos is possible. The lecture assumes knowledge of the statistical physics course and of parts of the higher quantum theory lecture.

In detail, following topics will be discussed (among others):
Monte Carlo, Molecular Dynamics, Path integral Monte Carlo, Car-Parrinello, "finite size scaling’’, phase transitions, cellular automata, growth models, simulations in astrophysics.

In the exercise groups some of the topics will be worked on in small groups of 2-3 students. The students should present their results in the final colloquium.
