Critical properties of the three- and four-dimensional gauge glass
Helmut G. Katzgraber, I. A. Campbell
The gauge glass in dimensions 3 and 4 is studied using a variety of numerical methods, in order to obtain accurate and reliable values for the critical parameters. Detailed compari…
Size dependence of the internal energy in Ising and vector spin glasses
Helmut G. Katzgraber, I. A. Campbell
We study numerically the scaling correction to the internal energy per spin as a function of system size and temperature in a variety of Ising and vector spin glasses. From a stand…
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…
On the existence of a finite-temperature transition in the two-dimensional gauge glass
Helmut G. Katzgraber
Results from Monte Carlo simulations of the two-dimensional gauge glass supporting a zero-temperature transition are presented. A finite-size scaling analysis of the correlation le…
Reversal-field memory in magnetic hysteresis
H. G. Katzgraber, F. Pazmandi, C. R. Pike +4
We report results demonstrating a singularity in the hysteresis of magnetic materials, the reversal-field memory effect. This effect creates a nonanalyticity in the magnetization c…
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…
