Three different vortex glass models are studied by examining the energy barrier against vortex motion across the system. In the two-dimensional gauge glass this energy barrier is found to increase logarithmically with system size which opens up for the existence of a low-temperature phase with zero resistivity. Associated with the large-energy barriers is a breaking of ergodicity which explains why the well-established results from equilibrium studies could fail. The behavior of the more…

We investigate the magnetic and glassy transitions of the square-lattice XY model in the presence of random phase shifts. We consider two different random-shift distributions: the Gaussian
