Atomic Cluster Expansion: Completeness, Efficiency and Stability

TL;DR: A fast recursive algorithm is provided for efficient evaluation of the derivation of polynomial basis functions for approximating isometry and permutation invariant functions, particularly with an eye to modelling properties of atomistic systems.
Journal ArticleDOI

Regularised atomic body-ordered permutation-invariant polynomials for the construction of interatomic potentials

TL;DR: In this article, the authors investigated the use of invariant polynomials in the construction of data-driven interatomic potentials for material systems and showed that the low dimensionality combined with careful regularization actually leads to better transferability than the high dimensional, kernel based Gaussian approximation potential.
Journal ArticleDOI

Guaranteed and robust a posteriori bounds for Laplace eigenvalues and eigenvectors: conforming approximations

TL;DR: Upper and lower bounds for an arbitrary simple eigenvalue are given and guaranteed, fully computable, optimally convergent, and polynomial-degree robust bounds on the energy error in the approximation of the associated eigenvector are derived.
Journal ArticleDOI

Guaranteed and robust a posteriori bounds for Laplace eigenvalues and eigenvectors: a unified framework

TL;DR: This paper develops a general framework for a posteriori error estimates in numerical approximations of the Laplace eigenvalue problem, applicable to all standard numerical methods, and extends it in an appendix to the generic class of bounded-below self-adjoint operators with compact resolvent.
Journal ArticleDOI

A perturbation-method-based a posteriori estimator for the planewave discretization of nonlinear Schrodinger equations

TL;DR: In this paper, a perturbation-based method is proposed to post-process the planewave approximation of the eigenmodes of periodic Schrodinger operators, and then use this post-processing to construct an accurate a posteriori estimator for the approximations of the (nonlinear) Gross-Pitaevskii equation, valid at each step of a selfconsistent procedure.
