Exact level structure of finite uniform Ising lattices: the density of states is a cut-size spectrum
Read PDFThe paper proves that unsatisfied Ising bonds are edge cuts of the down-spin set, turning the full finite-lattice level spectrum into a graph cut-size spectrum. It derives parity, edge-connectivity and bipartite-symmetry laws, level-count formulas, exact algorithms and exhaustive checks, while retaining the stated asymptotic and hardness limitations.
