Transverse correlation functions in the Ising antiferromagnet on the anisotropic kagome lattice — •Walter Apel¹ and Hans-Ulrich Everts² — ¹PTB Braunschweig, PSt4, 38116 Braunschweig — ²LUH, Inst. f. Theoret.Physik, 30167 Hannover

We study the anisotropic kagome Ising antiferromagnet, i.e. a model in which the coupling along one of the three directions differs from the couplings along the other two directions.

In previous work [J of Statistical Mechanics: Theory and Experiment 2011], we calculated rigorously the correlation function parallel to the chains. Now, we devise a method to calculate rigorously the correlation functions transverse to the chains. The phase diagram and first results for the correlation functions are given.
