Abstract
We use linked cluster series expansion methods to estimate the values of various short distance correlation functions in Heisenberg antiferromagnets at T=0, for dimension . The method incorporates the possibility of spontaneous symmetry breaking, which is manifest in . The results are important in providing a test for approximate theories of the antiferromagnetic ground state.
