A Quasi Time-Reversible scheme based on density matrix extrapolation on the Grassmann manifold for Born-Oppenheimer Molecular Dynamics
Federica Pes, Ètienne Polack, Patrizia Mazzeo +3
This article proposes a so-called Quasi Time-Reversible (QTR G-Ext) scheme based on Grassmann extrapolation of density matrices for an accurate calculation of initial guesses in Bo…
Embedded corrector problems for homogenization in linear elasticity
Virginie Ehrlacher, Frederic Legoll, Benjamin Stamm +1
In this article, we extend the study of embedded corrector problems, that we have previously introduced in the context of the homogenization of scalar diffusive equations, to the c…
A multipoint perturbation formula for eigenvalue problems
Geneviève Dusson, Louis Garrigue, Benjamin Stamm
Standard perturbation theory of eigenvalue problems consists of obtaining approximations of eigenmodes in the neighborhood of an operator where the corresponding eigenmode is known…
Reduced basis surrogates for quantum spin systems based on tensor networks
Paul Brehmer, Michael F. Herbst, Stefan Wessel +2
Within the reduced basis methods approach, an effective low-dimensional subspace of a quantum many-body Hilbert space is constructed in order to investigate, e.g., the ground-state…
