Bond and site defects in fully frustrated two-dimensional Ising systems

The Villain model and the triangular antiferromagnet are the two canonical fully frustrated two-dimensional Ising systems. Exact results are presented for the entropy changes that occur when bond and site defects are introduced into these systems. The results for single defects are obtained first. P...
