Low Energy Excitations in Spin Glasses from Exact Ground States
Matteo Palassini, Frauke Liers, Michael Juenger +1
We investigate the nature of the low-energy, large-scale excitations in the three-dimensional Edwards-Anderson Ising spin glass with Gaussian couplings and free boundary conditions…
Monte Carlo studies of the one-dimensional Ising spin glass with power-law interactions
H. G. Katzgraber, A. P. Young
We present results from Monte Carlo simulations of the one-dimensional Ising spin glass with power-law interactions at low temperature, using the parallel tempering Monte Carlo met…
Interface energies in Ising spin glasses
T. Aspelmeier, M. A. Moore, A. P. Young
The replica method has been used to calculate the interface free energy associated with the change from periodic to anti-periodic boundary conditions in finite-dimensional spin gla…
The stiffness exponent of two-dimensional Ising spin glasses for non-periodic boundary conditions using aspect-ratio scaling
Alexander K. Hartmann, Alan J. Bray, A. C. Carter +2
We study the scaling behavior of domain-wall energies in two-dimensional Ising spin glasses with Gaussian and bimodal distributions of the interactions and different types of bound…
Large-Scale, Low-Energy Excitations in the Two-Dimensional Ising Spin Glass
A. K. Hartmann, A. P. Young
We study large-scale, low-energy excitations in the Ising spin glass with Gaussian interactions in two-dimensions at zero temperature, using an optimization algorithm to determine…
Numerical studies of the two- and three-dimensional gauge glass at low temperature
Helmut G. Katzgraber, A. P. Young
We present results from Monte Carlo simulations of the two- and three-dimensional gauge glass at low temperature using the parallel tempering Monte Carlo method. Our results in two…
