We study the configurations of minimum energy among those with zero magnetisation in Ising spin glasses. We formulate that problem as a graph partitioning problem and we give an algorithm for it. We determine the concentration of negative interactions such that those configurations give a ground sta

The amount and nature of 2 particle-2 hole correlations in the ground state of I60 was investigated using various approximations. First 2fiw excitations were considered with the particles in the 2s-Id shell and the holes in the lp shell. Matrix diagonalization, with spurious states removed, resulted
