Computing resonances of perturbed Schrödinger equations: Application to Reissner-Norsdtröm-de Sitter black holes
Valentin Arrigoni, Geneviève Dusson
We present a numerical method for computing resonances of one-dimensional Schrödinger equations perturbed by a compactly supported potential, via finding zeros of the Wronskian as…

A posteriori error estimates for Schr{ö}dinger operators discretized with linear combinations of atomic orbitals
Geneviève Dusson, Mi-Song Dupuy, Ioanna-Maria Lygatsika
We establish guaranteed and practically computable a posteriori error bounds for source problems and eigenvalue problems involving linear Schr{ö}dinger operators with atom-centere…
