Solving the Bethe-Salpeter equation on massively parallel architectures
Xiao Zhang, Sebastian Achilles, Jan Winkelmann +3
The last ten years have witnessed fast spreading of massively parallel computing clusters, from leading supercomputing facilities down to the average university computing center. M…
ChASE: Chebyshev Accelerated Subspace iteration Eigensolver for sequences of Hermitian eigenvalue problems
Jan Winkelmann, Paul Springer, Edoardo Di Napoli
Solving dense Hermitian eigenproblems arranged in a sequence with direct solvers fails to take advantage of those spectral properties which are pertinent to the entire sequence, an…
Non-Linear Least-Squares Optimization of Rational Filters for the Solution of Interior Eigenvalue Problems
Jan Winkelmann, Edoardo Di Napoli
Rational filter functions can be used to improve convergence of contour-based eigensolvers, a popular family of algorithms for the solution of the interior eigenvalue problem. We p…
Parallel adaptive integration in high-performance functional Renormalization Group computations
Julian Lichtenstein, Jan Winkelmann, David Sánchez de la Peña +2
The conceptual framework provided by the functional Renormalization Group (fRG) has become a formidable tool to study correlated electron systems on lattices which, in turn, provid…
