Revisiting the Faddeev-Skyrme Model and Hopf Solitons [PDF]
A. Gorsky, M. Shifman, A. YungWe observe that the Faddeev-Skyrme model emerges as a low-energy limit of scalar QED with two charged scalar fields and a selfinteraction potential of a special form (inspired by supersymmetric QCD). Then we discuss possible Hopf solitons of the "twisted-toroidal" type.View original: http://arxiv.org/abs/1306.2364
