Density matrix renormalization group and wave function factorization for nuclei

By T. Papenbrock and D. J. Dean

Abstract

We employ the density matrix renormalization group (DMRG) and the wave function factorization method for the numerical solution of large scale nuclear structure problems. The DMRG exhibits an improved convergence for problems with realistic interactions due to the implementation of the finite algorithm. The wave function factorization of fpg-shell nuclei yields rapidly converging approximations that are at the present frontier for large-scale shell model calculations.Comment: Proceedings: INT Workshop on "Nuclear forces and the quantum many-body problem", Oct. 2004.
