Overcoming system-size limitations in spin glasses

Helmut G. Katzgraber, Mathias Koerner, Frauke Liers +1

In order to overcome the limitations of small system sizes in spin-glass simulations, we investigate the one-dimensional Ising spin chain with power-law interactions. The model has…

Universality-class dependence of energy distributions in spin glasses

Helmut G. Katzgraber, Mathias Koerner, Frauke Liers +2

We study the probability distribution function of the ground-state energies of the disordered one-dimensional Ising spin chain with power-law interactions using a combination of pa…

Reduction of Two-Dimensional Dilute Ising Spin Glasses

S. Boettcher, A. K. Hartmann

The recently proposed reduction method is applied to the Edwards-Anderson model on bond-diluted square lattices. This allows, in combination with a graph-theoretical matching algor…
