چکیده
We study the gauged Landau-Lifshitz model in which a suitably chosen triplet of background scalar fields is included. It is shown that the model admits solitonic configurations.

Stationary structures in two - dimensional Heisenberg ferromagnets .
Stationary structures in two-dimensional Heisenberg ferromagnets. Abstract Stationary structures in a classical isotropic two-dimensional Heisenberg ferromagnetic are studied in the framework of the (2+1)-dimensional Landau-Lifshitz model. It is established that in the case of S(r, t) = S(r − vt) the Landau-Lifshitz equation is closely related to the Ablowitz-Ladik hierarchy. This relation is u...
متن کاملStationary Structures in Two-Dimensional Continuous Heisenberg Ferromagnetic Spin System
Stationary structures in a classical isotropic two-dimensional continuous Heisenberg ferromagnetic spin system are studied in the framework of the (2 + 1)-dimensional Landau–Lifshitz model. It is established that in the case of ~ S(~r, t) = ~ S(~r − ~vt) the Landau–Lifshitz equation is closely related to the Ablowitz–Ladik hierarchy. This relation is used to obtain soliton structures, which are...
متن کاملChern-simons Quantum Field Representation of Planar Ferromagnets
1. Chern-Simons (CS) gauged models have recently attracted a great attention in the description of several phenomena in condensed matter physics as the Fractional Quantum Hall Effect (FQHE) and the High Temperature Superconductivity [1, 2]. In this context, models of the Landau-Ginzburg type have been proposed as effective field-theories [3, 4]. In the stationary limit, soliton solutions to the...
متن کاملReversal in Ferromagnetic Film Through Solitons by Electromagnetic Field
We study the reversal of magnetization in an isotropic ferromagnetic film free from charges by exposing it to a circularly polarized electromagnetic (EM) field. The magnetization excitations obtained in the form of line and lump solitons of the completely integrable modified KP-II equation which is derived using a reductive perturbation method from the set of coupled Landau-Lifshitz and Maxwell...
متن کاملScattering of magnetic solitons in two dimensions
Solitons which have the form of a vortex-antivortex pair have recently been found in the Landau-Lifshitz equation which is the standard model for the ferromagnet. We simulate numerically head-on collisions of two ferromagnetic solitons and observe a right angle scattering pattern which is familiar from relativistic models. We offer a resolution of this highly nontrivial dynamical behavior by ex...
