Evolution of Nuclear Many-Body Forces with the Similarity Renormalization Group

By E. D. Jurgenson, P. Navratil and R. J. Furnstahl

Abstract

The first practical method to evolve many-body nuclear forces to softened form using the Similarity Renormalization Group (SRG) in a harmonic oscillator basis is demonstrated. When applied to He4 calculations, the two- and three-body oscillator matrix elements yield rapid convergence of the ground-state energy with a small net contribution of the induced four-body force.Comment: 4 pages, 5 figures, PRL published versio
