Phys. Rev. Lett. 103, 082501 (2009) [4 pages]Evolution of Nuclear Many-Body Forces with the Similarity Renormalization GroupReceived 18 May 2009; published 18 August 2009 The first practical method to evolve many-body nuclear forces to softened form using the similarity renormalization group in a harmonic oscillator basis is demonstrated. When applied to 4He 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. © 2009 The American Physical Society URL:
