Dynamics of Baby Skyrmions
Baby Skyrmions are topological solitons in a (2+1)-dimensional field theory which resembles the Skyrme model in important respects. We apply some of the techniques and approximations commonly used in discussions of the Skyrme model to the dynamics of baby Skyrmions and directly test them against numerical simulations. Specifically we study the effect of spin on the shape of a single baby Skyrmi...
متن کاملCompact baby skyrmions
For the baby Skyrme model with a specific potential, compacton solutions, i.e., configurations with a compact support and parabolic approach to the vacuum, are derived. Specifically, in the non-topological sector, we find spinning Q-balls and Q-shells, as well as peakons. Moreover, we obtain compact baby skyrmions with non-trivial topological charge. All these solutions may form stable multi-so...
متن کاملBaby Skyrmions on the Sphere
We study a model for two-dimensional skyrmions on a sphere of radius L. Such model simulates a skyrmion lattice of density W/(2πL), where W is the skyrmion winding number. We show that, to a very good approximation, physical results depend only on the product αL, where α is the strength of potential term. In the range αL ∼ 3 the order parameter vanishes, there is a uniform distribution of the d...
متن کاملCollision–Induced Decay of Metastable Baby Skyrmions
Many extensions of the standard model predict heavy metastable particles which may be modeled as solitons (skyrmions of the Higgs field), relating their particle number to a winding number. Previous work has shown that the electroweak interactions admit processes in which these solitons decay, violating standard model baryon number. We motivate the hypothesis that baryon–number–violating decay ...
متن کاملBaby Skyrmions stabilized by vector mesons
Recent results suggest that multi-Skyrmions stabilized by ω mesons have very similar properties to those stabilized by the Skyrme term. In this paper we present the results of a detailed numerical investigation of a (2+1)-dimensional analogue of this situation. Namely, we compute solitons in an O(3) σ-model coupled to a massive vector meson and compare the results to baby Skyrmions, which are s...
