The imbalanced antiferromagnet in an optical lattice
arXiv:0908.0236 · doi:10.1103/PhysRevA.81.023628
Abstract
We study the rich properties of the imbalanced antiferromagnet in an optical lattice. We present its phase diagram, discuss spin waves and explore the emergence of topological excitations in two dimensions, known as merons, which are responsible for a Kosterlitz-Thouless transition that has never unambiguously been observed.
