Anyonic Bogomol'nyi solitons in a gauged O(3) sigma model.
The scale invariance of the O(3) sigma model can be broken by gauging a U(1) subgroup of the O(3) symmetry and including a Maxwell term for the gauge field in the Lagrangian. Adding also a suitable potential one obtains a field theory of Bogomol’nyi type with topological solitons. These solitons are stable against rescaling and carry magnetic flux which can take arbitrary values in some finite ...
متن کاملImplications of Sigma Models in the Standard Model and beyond * )
After a brief introduction to the sigma model in QCD, we discuss how the sigma model can be relevant in the Standard Model. It is shown to be useful in the analysis of weak processes, such as the study of ∆I = 1/2 rule, and in the analysis of the Higgs sector as well. The sigma model description is also shown to be quite useful in searching for the effects of New Physics via gauge boson self-in...
متن کاملNontopological thermal solitons in isotropic ferromagnetic lattices.
The paper deals with the properties of thermally excited solitons of the isotropic spin-S ferromagnetic chain with nearest-neighbor logarithmic interactions. The exact statistical mechanics of the interacting soliton gas is developed for the general case (arbitrary S, temperature and magnetic field). At low temperatures the model’s thermodynamics coincides with that of the Heisenberg model. We ...
متن کاملPolarized dark solitons in isotropic Kerr media
We characterize dark-type vector optical solitons of arbitrary polarization in isotropic, Kerr-type media by applying Hirota’s method to the integrable Manakov model with a defocusing nonlinearity. We find that nonuniformly polarized solitons comprise a rich solution family that can be divided into two categories: dark-dark and dark-bright vector solitons. We consider the propagation dynamics a...
متن کاملSolitons in supersymmetric sigma models with torsion
We derive a bound on the energy of the general (p,q)-supersymmetric two-dimensional massive sigma model with torsion, in terms of the topological and Noether charges that appear as central charges in its supersymmetry algebra. The bound is saturated by soliton solutions of first-order Bogomol'nyi-type equations. This generalizes results obtained previously for p = q models without torsion. We g...
