The theory of random matrices goes back to the 1960’s and has found applications in many branches of physics. In condensed matter physics, randommatrix theory can describe the universal properties of disordered metals and superconductors, dependent only on the presence or absence of fundamental symmetries in 10 symmetry classes (the socalled “tenfold way”). It was recently discovered that 5 out of these 10 symmetry classes have a topological invariant, which identifies distinct states of matter. Some of these topological superconductors and insulators have been realized in the laboratory. In this seminar we will discuss how randommatrix theory can be extended to account for topological properties.
