An economical method to calculate eigenvalues of the Schroedinger Equation
G. H. Rawitscher, I. Koltracht
The method is an extension to negative energies of a spectral integral equation method to solve the Schroedinger equation, developed previously for scattering applications. One imp…
A Novel Method for the Solution of the Schroedinger Eq. in the Presence of Exchange Terms
G. H. Rawitscher, S. Y. Kang, I. Koltracht +4
In the Hartree-Fock approximation the Pauli exclusion principle leads to a Schroedinger Eq. of an integro-differential form. We describe a new spectral noniterative method (S-IEM),…
High Accuracy Method for Integral Equations with Discontinuous Kernels
Sheon-Young Kang, Israel Koltracht, George Rawitscher
A new highly accurate numerical approximation scheme based on a Gauss type Clenshaw-Curtis Quadrature for Fredholm integral equations of the second kind, whose kernel is either dis…
Solution of Integral Equations by a Chebyshev Expansion Method
G. H. Rawitscher, I. Koltracht, R. A. Gonzales
A new spectral type method for solving the one dimensional quantum-mechanical Lippmann-Schwinger integral equation in configuration space is described. The radial interval is divid…
