Soliton Solutions of the Integrable Chiral Model in 2+1 Dimensions
Theodora Ioannidou
We present soliton and soliton-antisoliton solutions for the integrable chiral model in 2+1 dimensions with nontrivial (elastic) scattering. These solutions can be obtained either…

Soliton Dynamics in a Novel Discrete O(3) Sigma Model in (2+1) Dimensions
Theodora Ioannidou
The O(3) sigma model in two spatial dimensions admits topological (Bogomol'nyi) lower bound on its energy. This paper proposes a lattice version of this system which maintains the…
