Tensor solvers for high-dimensional eigenvalue problems  Y27  H 25
Speaker invited by: Christoph Schwab
Abstract: This talk focuses on the solution of high-dimensional eigenvalue problems, which arise, e.g. in quantum chemistry and in the modelling of quantum spin systems. The key assumption is that eigenvectors can be approximated in low-rank tensor formats. This a priori knowledge allows us to reduce the number of parameters and to improve the convergence of iterative methods. We present new iterative solvers that explicitly account for the low-rank structure of the eigenvectors and that are capable of computing hundreds of eigenstates in high dimensions. We showcase our method by solving vibrational Scrödinger equation as well as equations arising in density functional theory.
