Three-dimensional toroidal precession solitons with a nonzero Hopf index, which uniformly move along the anisotropy axis in a uniaxial ferromagnet, have been found. The structure and existence region of the solitons have been numerically determined by solving the Landau-Lifshitz equation. 
Three-dimensional magnetic solitons
Results are presented on the theoretical investigation of various three-dimensional structures in magnets, such as cnoidal and spiral hedgehogs in the Heisenberg model, localized textures, structures
Static Hopf Solitons and Knotted Emergent Fields in Solid-State Noncentrosymmetric Magnetic Nanostructures.
This work model the existence of such static solitons with different Hopf index values in noncentrosymmetric solid magnetic nanostructures with a perpendicular interfacial magnetic anisotropy and shows how this surface an isotropy, along with the Dzyaloshinskii-Moriya interactions and the geometry of nanostructure, stabilize hopfions.
Hopfion dynamics in chiral magnets
Resonant spin dynamics of topological spin textures are correlated with their topological nature, which can be employed to understand this nature. In this study, we present resonant spin dynamics of
Skyrmions and spirals in cubic chiral magnets
Magnetic skyrmions are two-dimensional topologicallyprotected spin textureswith particle like properties which may crystallize inlattices that are typically oriented perpendicular to the magnetic
Self-assembly and electrostriction of arrays and chains of hopfion particles in chiral liquid crystals
It is reported that three-dimensional skyrmions in the form of double-twist tori called ‘hopfions’, or ‘torons’ when accompanied by additional self-compensating defects, self-assemble into periodic arrays and linear chains that exhibit electrostriction in confined chiral nematic liquid crystals.
Skyrmion Lattices in Chiral Metal–organic Frameworks
Skyrmions are knot-like topologically-protected objects of use in data storage and low-energy smart devices. They can be generated by applying a magnetic field to certain chiral ferromagnets, with
Linked topological colloids in a nematic host
This work fabricates colloidal microparticle analogs of the classic examples of links studied in the field of topology, the Hopf and Solomon links, which are dispersed in nematic fluids that possess orientational ordering of anisotropic rod-like molecules.


Vortex rings in ferromagnets: Numerical simulations of the time-dependent three-dimensional Landau-L
Vortex ring solutions are presented for the Landau-Lifshitz equation, which models the dynamics of a three-dimensional ferromagnet. The vortex rings propagate at constant speed along their symmetry
Propagating Magnetic Vortex Rings in Ferromagnets
It is shown that bulk ferromagnets support propagating nonlinear modes that are analogous to the vortex rings, or ``smoke rings,'' of fluid dynamics. These are circular loops of magnetic vorticity
Closed-vortex-type solitons with Hopf index
The structure of three dimensional solitons with non-trivial Hopf index is investigated for the S2 nonlinear sigma -model. It is shown that the corresponding regular solutions are of closed-vortex
Static solitons with nonzero Hopf number
We investigate a generalized nonlinear O(3) {sigma} model in three space dimensions where the fields are maps from R{sup 3}{union}{l_brace}{infinity}{r_brace} to S{sup 2}. Such maps are classified by
We study the relation between the number of firms and market power in experimental oligopolies. Price competition under decreasing returns involves a wide interval of pure strategy equilibrium
