Abstract

Monte Carlo studies of the 3D random field XY model on simple cubic lattices of size 64³, using two different isotropic random-field probability distributions of moderate strength, show a glassy freezing behavior above T_c, and long-range order below T_c, consistent with our earlier results for weaker and stronger random fields. This model should describe random pinning in vortex lattices in type-II superconducting alloys, charge-density wave materials, and decagonal quasicrystals.
