Topological Q-solitons
نویسنده
چکیده
Static topologically-nontrivial configurations in sigma-models, for spatial dimension D ≥ 2, are unstable. The question addressed here is whether such sigma-model solitons can be stabilized by steady rotation in internal space; that is, rotation in a global SO(2) symmetry. This is the mechanism which stabilizes Q-balls (non-topological solitons). The conclusion is that the Q-mechanism can stabilize topological solitons in D = 2 spatial dimensions, but not for D = 3. ∗email: [email protected]

Small Q balls
We develop an adequate description of non-topological solitons with a small charge, for which the thin-wall approximation is not valid. There is no classical lower limit on the charge of a stable Q-ball. We examine the parameters of these small-charge solitons and discuss the limits of applicability of the semilcassical approximation. ∗ email address: [email protected] Non-topological solito...
متن کامل6 Hopf solitons and Hopf Q - balls on S 3
Field theories with a S 2-valued unit vector field living on S 3 × IR space-time are investigated. The corresponding eikonal equation, which is known to provide an integrable sector for various sigma models in different spaces, is solved giving static as well as time-dependent multiply knotted configurations on S 3 with arbitrary values of the Hopf index. Using these results, we then find a set...
متن کاملQ-balls in the MSSM
Non-topological solitons have been studied in a variety of models [1]. One particular type of such solitons, Q-balls [1,2], are present in the spectrum of a theory, whenever it satisfies the conditions outlined below. This class of theories includes the MSSM and other supersymmetric generalizations of the Standard Model. Surprisingly, the rich phenomenology associated with the solitonic sector ...
متن کاملSolitogenesis: Primordial Origin of Non-topological Solitons
We discuss the formation of nontopological solitons in a second-order phase transition in the early Universe. Ratios of dimensionless coupling constants in the Lagrangian determine their abundance and mass. For a large range of parameters, non-topological solitons can be cosmologically significant, contributing a significant fraction of the present mass density of the Universe. Submitted to Phy...
متن کاملTopological Switching and Orbiting Dynamics of Colloidal Spheres Dressed with Chiral Nematic Solitons
Metastable configurations formed by defects, inclusions, elastic deformations and topological solitons in liquid crystals are a promising choice for building photonic crystals and metamaterials with a potential for new optical applications. Local optical modification of the director or introduction of colloidal inclusions into a moderately chiral nematic liquid crystal confined to a homeotropic...
