The special configuration and dynamics known for interstitialcies in face-centered-cubic metals are exploited to construct a model giving all the thermodynamic properties of crystalline, liquid, and…
Phase transitions in coupled XY-Ising systems.
This work studies the critical behavior of fully frustrated XY and Josephson-junction systems by means of a coupled XY-Ising model, and finds separate XY and Ising and first-order transitions, depending on the parameters.
Critical behavior of coupled XY models.
Nonuniversal critical behavior and first-order transitions in a coupled XY-Ising model.
Conformal anomaly and critical exponents of the XY Ising model.
Critical exponents are obtained more accurately and are consistent with previous Monte Carlo simulations suggesting new critical behavior and with recent calculations for the frustrated $XY$ model.
Chiral exponents of the square-lattice frustrated XY model: A Monte Carlo transfer-matrix calculation.
The results support the identification of the critical behavior of this model with that along the line of transitions of simultaneous ordering or becoming critical of Ising and planar rotor degrees of freedom in the [ital XY]-Ising model studied recently.
Rate theory of dislocation motion: Thermal activation and inertial effects.
The enhanced plasticity in superconductors is explained by an increase in the average distance traveled by dislocations after thermal activation accounting for the dependence on both the viscosity and the temperature.

Charging effects and quantum crossover in granular superconductors.
It is argued that, in the presence of charge ordering, a nonmonotonic behavior with decreasing temperature is possible with a maximum in the resistance just before entering the superconducting phase.
Monte Carlo study of frustrated XY models on a triangular and square lattice.
