Numerical study of the two-replica overlap of the 3D Edwards–Anderson Ising spin glass

Berg, Bernd A; Billoire, Alain; Janke, Wolfhard - In: Physica A: Statistical Mechanics and its Applications 321 (2003) 1, pp. 49-58

We present results of recent high-statistics Monte Carlo simulations of the Edwards–Anderson Ising spin-glass model in three dimensions. The study is based on a non-Boltzmann sampling technique, the multi-self-overlap algorithm which is specifically tailored for sampling rare-event states. We...

Cluster-exact approximation of spin glass groundstates

Hartmann, Alexander K. - In: Physica A: Statistical Mechanics and its Applications 224 (1996) 3, pp. 480-488

We present a fast (∼ O (N3)) algorithm which calculates groundstates of Ising spin glasses approximately. It works by randomly selecting clusters of spins which exhibit no frustrations. The spins which were not selected, contribute to the local fields of the selected spins. For the...
