Fractional Skyrmion molecules in a model
Yutaka Akagi, Yuki Amari, Sven Bjarke Gudnason +2
We study fractional Skyrmions in a baby Skyrme model with a generalization of the easy-plane potential. By numerical methods, we find stable, metastable, and unstab…
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…
Some vortex solutions in the extended Skyrme-Faddeev model
L. A. Ferreira, M. Hayasaka, J. Jäykkä +2
Analytical and numerical vortex solutions for the extended Skyrme-Faddeev model in a (3+1) dimensional Minkowski space-time are investigated. The extension is obtained by adding to…
Vortices in the extended Skyrme-Faddeev model
L. A. Ferreira, J. Jäykkä, Nobuyuki Sawado +1
We construct analytical and numerical vortex solutions for an extended Skyrme-Faddeev model in a dimensional Minkowski space-time. The extension is obtained by adding to th…
Numerical Nahm transform for 2-caloron solutions
Daichi Muranaka, Atsushi Nakamula, Nobuyuki Sawado +1
A new numerical method for performing the Nahm transform for charge caloron is presented. The Weyl equations with boundary impurities are solved directly and the determinatio…
Static Hopfions in the extended Skyrme-Faddeev model
L. A. Ferreira, Nobuyuki Sawado, Kouichi Toda
We construct static soliton solutions with non-zero Hopf topological charges to a theory which is an extension of the Skyrme-Faddeev model by the addition of a further quartic term…
