Abstract
New results are reported for the ground-state configurations of the Faddeev -Skyrme model. We started minimization runs on a large set of initial state s and found topologically new ground states for the Hopf charges Q = 4 and 5, and a symmetry-breaking deformation for Q = 6. The corresponding energie s improve the fit to the Vakulenko-Kapitanskii behavior E proportional to \ Q\(3/4).
