Description

First I will give a short comparison of topological defects and topological solitons for various space dimensions (D=1,2,3). Then I will discuss properties of 2-dimensional solitons for U(1) gauged easy-axis Heisenberg antiferromagnet, compare these solitons both with 2D Nielsen-Olesen strings in the Abelian Higgs model and with 2D Belavin-Polyakov solitons in isotropic antiferromagnet model - and will show their dynamical stability.
