Spin glass, a class of random magnets with competing ferromagnetic and antiferromagnetic
interactions, has extensively been studied both experimentally and theoretically for more …

Detailed account is given of the chirality scenario of experimental spin-glass transitions. In
this scenario, the spin glass order of weakly anisotropic Heisenberg-like spin-glass magnets …

Spin and chirality orderings of a three-dimensional XY spin glass are studied by extensive

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 …

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 …

We study numerically the superconductor to insulator transition in two-dimensional phase-
glass (or chiral-glass) models with varying degree of disorder. These models describe the …

We investigate numerically the resistive transition in the two-dimensional XY gauge glass
model. The resistively shunted junction dynamics subject to the fluctuating twist boundary …

Phase coherence and vortex order in a Josephson-junction array at irrational frustration are

The ordering of the three-dimensional isotropic XY spin glass with nearest-neighbor random
Gaussian coupling is studied by extensive Monte Carlo simulations. To investigate the …
