Derrick’s scaling argument G.H.Derrick, J.Math.Phys.5,1252 (1964), ``Comments on nonlinear wave equations as models for elementary particles’’ Scaling: Consider a model of scalar field: We need to introduce form of a potential to stabilize the solution.

The baby-skyrmion potential Plug into the equation it is written as Assume the zero curvature condition

Analytical solutions for n = 1, 2
12

14
The charge per unit length: The components:
15
Broken axisymmetry of the solution Symmetric: The baby-skyrmion exhibits a non-axisymmetric solution depending on a choice of potential I.Hen et. al, Nonlinearity 21 (2008) 399
16
A repulsive force between the core of the vortices might appear It might be similar with the force between the Abrikosov vortex. Erick J.Weinberg, PRD19,3008 (1979), ``Multivortex solutions of the Ginzburg-Landau equations” The vortex matter/lattice structure is observed.
