Numerical Methods
Abstract: This lecture gives an overview of numerical methods that are important for the theoretical physicist. In a first part, we will cover generally applicable basic methods like matrix diagonalization or integration of differential equations. In the second part we will proceed to methods like exact diagonalization or quantum Monte Carlo that are suitable for solving model Hamiltonians in condensed matter physics. We will focus on algorithms and occasionally discuss available software or libraries and methods of implementation.

Nanostructured Materials
Abstract: Nanostructured materials have been shown in recent years to possess fascinating new properties as well as large potential for applications in technology. This class of materials including nanotubes, nanocrystals and nanostructured thin films will be discussed from a theoretical point of view. It will be analyzed how their mechanical, transport, thermodynamic, and optical properties depend on the particle size and assembly. Varying these parameters yields a wide range of properties, giving rise to the possibility of designing materials with given specifications.

WS 2004/05

Atomistic Simulation of Material Properties
Abstract: The microscopic investigation of material properties at finite temperature, under the influence of mechanical stress or optical excitation often depends, due to the large number of degrees of freedom, on classical or semiclassical simulation methods. This lecture will cover in detail widely used methods of molecular dynamics simulation on the basis of classical interaction potentials as well as tight binding and the embedded atom method. The application to modern problems of materials science will be treated extensively.
