Mock-integrability and stable solitary vortices
Yukito Koike, Atsushi Nakamula, Akihiro Nishie +4
Localized soliton-like solutions to a -dimensional hydro-dynamical evolution equation are studied numerically. The equation is so-called Williams-Yamagata-Flierl equation, w…
Generalized Volterra lattices: binary Darboux transformations and self-consistent sources
Folkert Müller-Hoissen, Oleksandr Chvartatskyi, Kouichi Toda
We study two families of (matrix versions of) generalized Volterra (or Bogoyavlensky) lattice equations. For each family, the equations arise as reductions of a partial differentia…
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…
