Absence of an Almeida-Thouless line in Three-Dimensional Spin Glasses
A. P. Young, Helmut G. Katzgraber
We present results of Monte Carlo simulations of the three-dimensional Edwards-Anderson Ising spin glass in the presence of a (random) field. A finite-size scaling analysis of the…
Correlation Length of the Two-Dimensional Ising Spin Glass with Gaussian Interactions
Helmut G. Katzgraber, L. W. Lee, A. P. Young
We study the correlation length of the two-dimensional Ising spin glass with a Gaussian distribution of interactions, using an efficient Monte Carlo algorithm proposed by Houdayer,…
Lack of Ultrametricity in the Low-Temperature phase of 3D Ising Spin Glasses
Guy Hed, A. P. Young, Eytan Domany
We study the low-temperature spin-glass phases of the Sherrington-Kirkpatrick (SK) model and of the 3-dimensional short range Ising spin glass (3dISG). For the SK model, evidence f…
Geometry of large-scale low-energy excitations in the one-dimensional Ising spin glass with power-law interactions
Helmut G. Katzgraber, A. P. Young
Results are presented for the geometry of low-energy excitations in the one-dimensional Ising spin chain with power-law interactions, in which the model parameters are chosen to yi…
Numerical studies of the 2 and 3D gauge glass at low temperature
Helmut G. Katzgraber
We report results from Monte Carlo simulations of the two- and three-dimensional gauge glass at low temperature using parallel tempering Monte Carlo. In two dimensions, we find str…
