Abstract

The aloof baby Skyrme model is a (2+1)-dimensional theory with solitons that are lightly bound. It is a low-dimensional analogue of a similar Skyrme model in (3+1)- dimensions, where the lightly bound solitons have binding energies comparable to nuclei. A previous study of static solitons in the aloof baby Skyrme model revealed that multi-soliton bound states have a cluster structure, with constituents that preserve their individual identities due to the short-range repulsion and long-range attraction between solitons. Furthermore, there are many different local energy minima that are all well-described by a simple binary species particle model. In this paper we present the first results on soliton dynamics in the aloof baby Skyrme model. Numerical field theory simulations reveal that the lightly bound cluster structure results in a variety of exotic soliton scattering events that are novel in comparison to standard Skyrmion scattering. A dynamical version of the binary species point particle model is shown to provide a good qualitative description of the dynamics.

Baby Skyrmions stabilized by vector mesons

Journal Article Foster, David ; Sutcliffe, Paul - Physical Review. D, Particles Fields

Recent results suggest that multi-Skyrmions stabilized by {omega} 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) {sigma} model coupled to a massive vector meson and compare the results to baby Skyrmions, which are solitons in an O(3) {sigma} model including a Skyrme term. We find that multisolitons in the vector meson model are surprisingly similar to those in the baby Skyrme model, and we explain this correspondence using a simplemore » derivative expansion.« less

Solitons in a baby-Skyrme model with invariance under area-preserving diffeomorphisms

Journal Article Gisiger, T ; Paranjape, M B - Physical Review, D

We study the properties of soliton solutions in an analogue of the Skyrme model in 2+1 dimensions whose Lagrangian contains the Skyrme term and the mass term, but no usual kinetic term. The model admits a symmetry under area-preserving diffeomorphisms. We solve the dynamical equations of motion analytically for the case of spinning isolated baryon-type solitons. We take fully into account the induced deformation of the spinning Skyrmions and the consequent modification of its moment of inertia to give an analytical example of related numerical behavior found by Piette, Schroers, and Zakrzewski. We solve the equations of motion also formore »« less

Remarks on baby Skyrmion Lie-algebraic generalization

Journal Article Sheu, Chao-Hsiang ; Shifman, Mikhail - Physical Review. D.

We discuss generalized baby Skyrmions emerging in a (1+2)-dimensional σ model with a certain Lie-algebraic structure. The same result applies to the Polyakov-Belavin instantons in D = 1 + 1. The O(3) symmetry of the target space is lost, but O(2) is preserved in the simplest model under consideration. Both the topological charge and the soliton mass (the instanton action) are determined. Of special interest are limiting cases of the deformation parameter k (also referred to as the elongation parameter). If |k–1|<<1, we arrive at a model which is studied in condensed matter. If k>>1, we obtain the so-called cigar,more »« less

Investigation of restricted baby Skyrme models

Journal Article Adam, C ; Romanczukiewicz, T ; Wereszczynski, A ; ... - Physical Review. D, Particles Fields

A restriction of the baby Skyrme model consisting of the quartic and potential terms only is investigated in detail for a wide range of potentials. Further, its properties are compared with those of the corresponding full baby Skyrme models. We find that topological (charge) as well as geometrical (nucleus/shell shape) features of baby Skyrmions are captured already by the soliton solutions of the restricted model. Further, we find a coincidence between the compact or noncompact nature of solitons in the restricted model, on the one hand, and the existence or nonexistence of multi-Skyrmions in the full baby Skyrme model, onmore » the other hand.« less

A remark on spin and statistics of baby skyrmion

Journal Article Otsu, H ; Sato, T - Modern Physics Letters A; (United States)

The authors study spin and statistics of baby skyrmion, which is a topological soliton solution in the (2 + 1)-dimensional O(3) {sigma}-model. In this paper it is shown that the Hopf term written in terms of CP variables does not naively represent the topological charge associated with the non-triviality of {Pi}{sub 1} (S{sup 2} {r arrow} S{sup 2}). It is also pointed out, therefore, that the baby skyrmion cannot behave as anyon, even if the Hopf term written in terms of CP variables is added to the model.
