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…
Supercurrent coupling destabilizes knot solitons
J. M. Speight, J. Jäykkä
In an influential paper of 2002, Babaev, Faddeev and Niemi conjectured that two-component Ginzburg-Landau (TCGL) theory in three dimensions should support knot solitons, where the…
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…
