چکیده
We describe the kink solitary waves of a massive nonlinear sigma model with an S2 sphere as the target manifold. Our solutions form a moduli space of nonrelativistic solitary waves in the long wavelength limit of ferromagnetic linear spin chains.

Massive Nonlinear Sigma Models and BPS Domain Walls in Harmonic Superspace
Four-dimensional massive N = 2 nonlinear sigma models and BPS wall solutions are studied in the off-shell harmonic superspace approach in which N = 2 supersymmetry is manifest. The general nonlinear sigma model can be described by an analytic harmonic potential which is the hyper-Kähler analog of the Kähler potential in N = 1 theory. We examine the massive nonlinear sigma model with multi-cente...
متن کاملMulti-Domain Walls in Massive Supersymmetric Sigma-Models
Massive maximally-supersymmetric sigma models are shown to exhibit multiple static kink-domain wall solutions that preserve 1/2 of the supersymmetry. The kink moduli space admits a natural Kähler metric. We examine in some detail the case when the target of the sigma model is given by the co-tangent bundle of CP equipped with the Calabi metric, and we show that there exist BPS solutions corresp...
متن کاملSemi-classical mass of quantum k-component topological kinks
We use the generalized zeta function regularization method to compute the one-loop quantum correction to the masses of the TK1 and TK2 kinks in a deformation of the O(N) linear sigma model on the real line.

We consider topological solitons in the CP sigma models in two space dimensions. In particular, we study “kinks”, which are independent of one coordinate up to a rotation of the target space, and “chains”, which are periodic in one coordinate up to a rotation of the target space. Kinks and chains both exhibit constituents, similar to monopoles and calorons in SU(n) Yang-Mills-Higgs and Yang-Mil...
متن کاملForm factors of the sausage model obtained with bootstrap fusion from sine-Gordon theory.
We continue the investigation of massive integrable models by means of the bootstrap fusion procedure, started in our previous work on O(3) nonlinear sigma model. Using the analogy with SU(2) Thirring model and the O(3) nonlinear sigma model we prove a similar relation between sine-Gordon theory and a one-parameter deformation of the O(3) sigma model, the sausage model. This allows us to write ...
