Hysteretic memory effects in disordered magnets
Helmut G. Katzgraber, Gergely T. Zimanyi
We study the return point as well as the complementary point memory effects numerically with paradigmatic models for random magnets and show that already simple systems with Ising…
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…
Dynamical scaling in Ising and vector spin glasses
Helmut G. Katzgraber, I. A. Campbell
We have studied numerically the dynamics of spin glasses with Ising and XY symmetry (gauge glass) in space dimensions 2, 3, and 4. The nonequilibrium spin-glass susceptibility and…
