Single- and coupled-channel radial inverse scattering with supersymmetric transformations
Daniel Baye, Jean-Marc Sparenberg, Andrey M Pupasov-Maksimov +1
The present status of the coupled-channel inverse-scattering method with supersymmetric transformations is reviewed. We first revisit in a pedagogical way the single-channel case,…
Quadrupole transitions in the bound rotational-vibrational spectrum of the hydrogen molecular ion
Horacio Olivares Pilón, Daniel Baye
The three-body Schrödinger equation of the H hydrogen molecular ion with Coulomb potentials is solved in perimetric coordinates using the Lagrange-mesh method. The Lagrange-m…
Multichannel coupling with supersymmetric quantum mechanics and exactly-solvable model for Feshbach resonance
J. -M. Sparenberg, B. F. Samsonov, F. Foucart +1
A new type of supersymmetric transformations of the coupled-channel radial Schroedinger equation is introduced, which do not conserve the vanishing behavior of solutions at the ori…
Equivalence of the Siegert-pseudostate and Lagrange-mesh R-matrix methods
D. Baye, J. Goldbeter, J. -M. Sparenberg
Siegert pseudostates are purely outgoing states at some fixed point expanded over a finite basis. With discretized variables, they provide an accurate description of scattering in…
