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…

Inverse resonance problem on the line for perturbations of Pöschl-Teller potentials
Valentin Arrigoni
We study an inverse resonance problem on the line in which we aim at determining a compactly supported and integrable perturbation of a fixed Pöschl-Teller potential. We define th…
