Isolated Skyrmions in the nonlinear -model with a Dzyaloshinskii-Moriya type interaction
Yutaka Akagi, Yuki Amari, Nobuyuki Sawado +1
We study two dimensional soliton solutions in the nonlinear -model with a Dzyaloshinskii-Moriya type interaction. First, we derive such a model as a continuous limit of t…
Statistical nature of Skyrme-Faddeev models in dimensions and normalizable fermions
Yuki Amari, Masaya Iida, Nobuyuki Sawado
The Skyrme-Faddeev model has planar soliton solutions with target space . An Abelian Chern-Simons term (the Hopf term) in the Lagrangian of the model plays a crucial…
Knot Solitons: Hopfions in the Skyrme-Faddeev-Niemi model
Yuki Amari, Nobuyuki Sawado
We discuss the existence of knot solitons (Hopfions) in a Skryme-Faddeev-Niemi-type model on the target space , which can be viewed as an effective theory of both the…
Self-Dual Skyrmions on the Spheres
Y. Amari, L. A. Ferreira
We construct self-dual sectors for scalar field theories on a -dimensional Minkowski space-time with target space being the -dimensional sphere . The constr…
