Abstract
In the continuum O(3) sigma model in two spatial dimensions, there are
topological solitons whose size can be stabilized by adding Skyrme an
d potential terms. This Letter describes a lattice version, namely a n
atural way of modifying the 2D Heisenberg model to achieve topological
stability on the lattice.
