Ground-state clusters of two-, three-, and four-dimensional +/-J Ising spin glasses.
A huge number of independent true ground-state configurations is calculated for two-, three- and four-dimensional +/-J spin-glass models. Using the genetic cluster-exact approximation method, system sizes up to N=20(2),8(3),6(4) spins are treated. A "ballistic-search" algorithm is applied, which allows even for large system sizes to identify clusters of ground states that are connected by chain...
متن کاملConfiguration Memory in Patchwork Dynamics for Low-dimensional Spin Glasses
A patchwork method is used to study the dynamics of loss and recovery of an initial configuration in spin glass models in dimensions d = 1 and d = 2. The patchwork heuristic is used to accelerate the dynamics to investigate how models might reproduce the remarkable memory effects seen in experiment. Starting from a ground state configuration computed for one choice of nearest neighbor spin coup...
متن کاملGround State Incongruence in 2D Spin Glasses Revisited
A construction supporting a conjecture that different ground state pairs exist in the 2-dimensional Edwards-Anderson Ising spin glass is presented.
متن کاملEnergetics of clusters in the two-dimensional Gaussian Ising spin glass
We study numerically the properties of local low-energy excitations in the twodimensional Ising spin glass with Gaussian couplings. Given the ground state, we determine the lowest-lying connected cluster of flipped spins containing one given spin, either with a fixed volume, or with a volume constrained to lie in a certain range. Our aim is to understand corrections to the scaling predicted by ...
متن کاملNature of ground state incongruence in two-dimensional spin glasses
We rigorously rule out the appearance of multiple domain walls between ground states in 2D Edwards-Anderson Ising spin glasses (with periodic boundary conditions and, e.g., Gaussian couplings). This supports the conjecture that there is only a single pair of ground states in these models.
