Efficient and Accurate Algorithms for Solving the Bethe-Salpeter Eigenvalue Problem for Crystalline Systems

Peter Benner, Carolin Penke

Optical properties of materials related to light absorption and scattering are explained by the excitation of electrons. The Bethe-Salpeter equation is the state-of-the-art approac…

GR decompositions and their relations to Cholesky-like factorizations

Peter Benner, Carolin Penke

For a given matrix, we are interested in computing GR decompositions $A = GR$ , where $G$ is an isometry with respect to given scalar products. The orthogonal QR decomposition is the…
