Scattering of periodic solitons
R. J. Cova, W. J. Zakrzewski
With the help of numerical simulations we study N-soliton scattering (N=3,4) in the (2+1)-dimensional CP^1 model with periodic boundary conditions. When the solitons are scattered…
Weierstrass P-lumps
RJ Cova, WJ Zakrzewski
We present our results of a numerical investigation of the behaviour of a system of two solitons in the (2+1) dimensional model on a torus. Defined by the elliptic function…
Lump Scattering on a Torus
RJ Cova
Head-on collisions between two solitons in the pure model on a flat torus are investigated via numerical simulations. The charge-two lumps, written out in terms of Weierstra…
Splitting solitons on a torus
R. J. Cova
New CP1-soliton behaviour on a flat torus is reported. Defined by the Weierstrass elliptic function and numerically-evolved from rest, each soliton splits up in two lumps which eve…
Soliton scattering in the O(3) model on a torus
R. J. Cova, W. J. Zakrzewski
Using numerical simulations, the stability and scattering properties of the O(3) model on a two-dimensional torus are studied. Its solitons are found to be unstable but can be stab…
Skyrmions scattering in (2+1)-dimensions
R. J. Cova
The scattering properties of the non-linear model in (2+1)-D, modified by the addition of both a potential-like term and a Skyrme-like term, are considered. Most of the work…
