DensityMatrix Expansion for an Effective Nuclear Hamiltonian
Abstract
An expansion for the nuclear wavefunction density matrix in relative and c.m. coordinates is developed such that the leading term is the corresponding nuclearmatter density matrix at the local neutron and proton density. Truncation of all derivatives beyond second order yields an extremely simple form for the energy density which retains all the computational simplicity of the modified δ interaction and the Skyrme force, while maintaining contact with nuclearmatter theory based on a realistic interaction and reproducing the results of morecomplicated densitydependent HartreeFock calculations.
