Abstract

A continuum perturbative analysis and the Schwinger-boson mean-field theory are used to evaluate the ground-state energy of the two-dimensional Heisenberg antiferromagnet in the presence of background topological density. The spin-wave spectrum is bunched into Landau levels. The gauge charge of the Schwinger bosons is half the charge of the Holstein-Primakoff spin waves. The mean-field Skyrmion creation energy vanishes with the ordered moment at the disordering transition.
