The construction of axially symmetric soliton solutions with non-zero Hopf topological charges according to a theory known as the extended Skyrme-Faddeev model, was performed in [1]. In this paper we show how masses of glueballs are predicted within this model.

The superpotential for n-step soliton solution is derived in the case of an arbitrary dimensional projector for axially symmetric, static solution of nonlinear principal SU (N) σ-models. This was done by using an inverse scattering method developed by Belinski and Zakharov. Finite energy solutions are constructed for all SU (N) one soliton solutions generated by a single step.

We have found an approach to constructing a novel class of Laguerre-Gaussian (LG) beam using a superposition of the known single accessible soliton solutions. Choosing appropriate values of soliton parameter, one can make up novel LG beams, such as asymmetric necklace beams and gear beams. The shape of superposition beams can be controlled by picking different topological charges.

We explore the higher topological charge sector for generalized SU(2) Skyrme models in search of the static-field configuration with the lowest energy that would better reproduce what is expected for nuclei. Indeed the Skyrme model leads, for example, to toroidal, tetrahedral, and cubic symmetries for B = 2, 3, and 4 configurations, respectively, whereas nucleons in nuclei are presumably preserving their individuality. It turns out that the symmetries of the soliton solutions for the extended Skyrme models presented in this work are the same as for the Skyrme model at least for topological charges B < 5, which suggest that the Skyrme model has to be modified significantly to preserve the individual nature of the nucleons in nuclei.

The Skyrme–Faddeev model is a modified sigma model in three-dimensional space, which has string-like topological solitons classified by the integer-valued Hopf charge. Numerical simulations are performed to compute soliton solutions for Hopf charges up to 16, with initial conditions provided by families of rational maps from the three-sphere into the complex projective line. A large number of new solutions are presented, including a variety of torus knots for a range of Hopf charges. Often these knots are only local energy minima, with the global minimum being a linked solution, but for some values of the Hopf charge they are good candidates for the global minimum energy solution. The computed energies are in agreement with Ward's conjectured energy bound.

Introducing the Lax pair, it is shown that the Brans–Dicke equation is integrable for space-times with two commuting Killing vectors. Using the inverse-scattering method given by Belinskii and Zakharov, the n soliton solutions for the case of the time-dependent metric are introduced. Specially, the one and two travelling-wave-type solitonic solutions are obtained. Also it is shown that the method could be applied to the case of stationary axially symmetric space-times with two commuting Killing vectors. PACS Nos.: 04.20jb, 04.50+h
