A hybrid Chebyshev-Tucker tensor format for approximation of multivariate functions
Peter Benner, Boris N. Khoromskij, Venera Khoromskaia +1
We introduce and analyze a mesh-free two-level hybrid Chebyshev-Tucker tensor representation for approximating multivariate functions, which combines tensor-product Chebyshev inter…

Efficient Krylov methods for linear response in plane-wave electronic structure calculations
Michael F. Herbst, Bonan Sun
We propose a novel algorithm based on inexact GMRES methods for linear response calculations in density functional theory. Such calculations require iteratively solving a nested li…
