Resonant-state solution of the Faddeev-Merkuriev integral equations for three-body systems with Coulomb potentials
Z. Papp, J. Darai, C-. Y. Hu +3
A novel method for calculating resonances in three-body Coulombic systems is proposed. The Faddeev-Merkuriev integral equations are solved by applying the Coulomb-Sturmian separabl…
Three-potential formalism for the three-body scattering problem with attractive Coulomb interactions
Z. Papp, C-. Y. Hu, Z. T. Hlousek +2
A three-body scattering process in the presence of Coulomb interaction can be decomposed formally into a two-body single channel, a two-body multichannel and a genuine three-body s…
Variational separable expansion scheme for two-body Coulomb-scattering problems
J. Darai, B. Gyarmati, B. Kónya +1
We present a separable expansion approximation method for Coulomb-like potentials which is based on Schwinger variational principle and uses Coulomb-Sturmian functions as basis sta…
On the Coulomb Sturmian matrix elements of relativistic Coulomb Green's operators
B. Kónya, Z. Papp
The Hamiltonian of the radial Coulomb Klein-Gordon and second order Dirac equations are shown to possess an infinite symmetric tridiagonal matrix structure on the relativistic Coul…
Resonant-state solution of the Faddeev-Merkuriev integral equations for three-body systems with Coulomb-like potentials
Z. Papp, S. L. Yakovlev, C-. Y. Hu +3
A novel method for calculating resonances in three-body Coulombic systems is presented. The Faddeev-Merkuriev integral equations are solved by applying the Coulomb-Sturmian separab…
Continued fraction representation of the Coulomb Green's operator and unified description of bound, resonant and scattering states
B. Kónya, G. Lévai, Z. Papp
If a quantum mechanical Hamiltonian has an infinite symmetric tridiagonal (Jacobi) matrix form in some discrete Hilbert-space basis representation, then its Green's operator can be…
