Abstract

We present simulations of one- and two-vacancy states in a two-dimensional square-lattice Ising antiferromagnet. We find that the energy of the single-vacancy ground state scales as J2/3, where J is the spin-spin coupling. The S- and P-wave states of two vacancies are bound, with binding energy scrE∝J2/3 and J, respectively, while the D-wave state is unbound.
