Generalised meshes for quantum mechanical problems
TL;DR: A new method to discretise Schrodinger equations on a mesh based on an accurate approximation of a variational calculation and applications to many-body problems indicate that the accuracy of the results is improved by an order of magnitude with respect to conventional mesh calculations.

A numerical approach to nuclear shell-model calculations
TL;DR: An application of the Lanczos algorithm for the matrix eigenproblem to nuclear shell-model calculations is described, which has many advantages over conventional shell- model techniques, one of the most important being a very much slower growth of computation time with increasing dimensionality of theshell-model basis.

Variational buildup of nuclear shell model bases
T Sebe,J Nachamkin +1 more
TL;DR: In this paper, a truncation of the complete vector space is proposed for low-lying eigenvalues and eigenfunctions in the shell model, where a properly chosen initial vector is operated upon iteratively, generating a basis in which the Hamiltonian matrix is tridiagonal.
