Statistisk fysik

This course describes the themal properties of several systems in equilibrium. The models and their relevance for physical system that are treated include: the Ising, XY and Heisenberg models. Basic principles such as magnetism, superfluidity, first and second order phase transistions, symmetry breaking, order parameter, scaling and universality classes. Treatment of models in terms of Landau's mean field theory and it's limitations, and Kosterlitz Thouless phase transitions.
