COURSE GOALS: The aim of the course Physics of Disordered Systems is to provide an introduction to the key concepts and phenomena in describing disordered systems in physics and other disciplines. Disordered structures that are selfsimilar on certain length scales are very common in nature. They can be found on the largest and the smallest scales: in galaxies and landscapes, in aggregates and colloids, in glasses and polymers, in proteins and other large molecules. Models and theories developed to describe disordered systems in physics are widely used in the other areas. Student is first introduced to the concept of order parameter. Then two widely used concepts of fractal and percolation are explained. Finally, glasses and disordered magnets are described.
