Isospinning hopfions
Derek Harland, Juha Jäykkä, Yakov Shnir +1
The problem of constructing internally rotating solitons of fixed angular frequency in the Faddeev-Skyrme model is reformulated as a variational problem for an energy-like func…
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…
Scattering of knotted vortices (Hopfions) in the Faddeev-Skyrme model
J. Hietarinta, J. Palmu, J. Jäykkä +1
Several materials, such as ferromagnets, spinor Bose-Einstein condensates, and some topological insulators, are now believed to support knotted structures. One of the most successf…
Broken Baby Skyrmions
Juha Jäykkä, Martin Speight, Paul Sutcliffe
The baby Skyrme model is a (2+1)-dimensional analogue of the Skyrme model, in which baryons are described by topological solitons. In this paper we introduce a version of the baby…
Knot solitons in modified Ginzburg-Landau model
Juha Jäykkä, Joonatan Palmu
We study a modified version of the Ginzburg-Landau model suggested by Ward and show that Hopfions exist in it as stable static solutions, for values of the Hopf invariant up to at…
