The three-dimensional gauge-glass model
Vincenzo Alba, Ettore Vicari
We investigate the temperature-disorder (T-S) phase diagram of a three-dimensional gauge glass model, which is a cubic-lattice nearest-neighbor XY model with quenched random phase…

Quasi-long-range order in the 2D XY model with random phase shifts
Vincenzo Alba, Andrea Pelissetto, Ettore Vicari
We study the square-lattice XY model in the presence of random phase shifts. We consider two different disorder distributions with zero average shift and investigate the low-temper…
