We numerically study the energetics and atomic mechanisms of misfit dislocation nucleation and stress relaxation in a two-dimensional atomistic model of strained epitaxial layers on a substrate with… Expand

Current-voltage scaling of chiral and gauge-glass models of two-dimensional superconductors

- E. Granato
- Physics
- 29 August 1998

The scaling behavior of the current-voltage characteristics of chiral and gauge glass models of disordered superconductors, are studied numerically, in two dimensions. For both models, the linear… Expand

Resistivity scaling and critical dynamics of fully frustrated Josephson-junction arrays with on-site dissipation

- E. Granato, D. Domínguez
- Physics
- 8 February 2005

We study the scaling behavior and critical dynamics of the resistive transition in Josephson-junction arrays, at f=1/2 flux quantum per plaquette, by numerical simulation of an on-site dissipation… Expand

Phase transitions in a frustrated XY model with zig-zag couplings

- M. Benakli, E. Granato
- Physics
- 6 January 1997

We study a generalized version of the square-lattice frustrated XY model where unequal ferromagnetic and antiferromagnetic couplings are arranged in a zig-zag pattern. The ratio between the couplings… Expand
