'Numerical Methods for Many-Particle Systems' (Graduate)Held at the Institute for Theoretical Physics, University of Cologne (March 2012).
In conjunction with the Bonn-Cologne Graduate School of Physics and Astronomy.
LecturersDr. Andrew Mitchell, Priv.-Doz. Dr. Ralf Bulla, Prof. Dr. Simon Trebst
Course SummaryThis intensive course is intended to provide both a working understanding and real hands-on experience with the essential numerical techniques of solid state many-body physics.
Rather than a 'black-box' philosophy, the course aims to discuss the theory and physics underpinning numerical approaches. Lectures will introduce models of central importance, such as the Ising model, the Anderson impurity model, the Hubbard model and the Heisenberg model. Using these as concrete examples, the Monte Carlo, Exact Diagonalization, Numerical Renormalization Group and Density Matrix Renormalization Group techniques will be discussed. Students will also gain supervised practical hands-on experience writing, using and modifying simple computer codes to solve real problems.
