Monte Carlo study of a vortex glass model
نویسندگان
چکیده
We describe results of Monte Carlo simulations on a model that seems to have the necessary ingredients to describe a disordered type-II superconductor in a magnetic field. We compute the free energy cost to twist the direction of the phase of the condensate and analyze the results by finite-size scaling. The results show convincingly that the model has different behavior as a function of dimension: in d = 4 the model clearly has a finite transition temperature; Tc, while for d = 2 only there is only a transition at T = 0.

Characteristics of lead glass for radiation protection purposes: A Monte Carlo study
Background: Lead glass has a wide variety of applications in radiation protection. This study aims to investigate some characteristics of lead glass such as the γ-ray energy-dependent mass and linear attenuation coefficients, the half-value layer thickness, and the absorbed dose distribution for specific energy. Materials and Methods: The attenuation parameters of different lead glass types aga...
متن کاملThe Vortex Glass
The recently proposed state of a disordered type-II superconductor in a magnetic eld, the \vortex glass", is discussed and compared with the \spin glass" transition in magnetic systems. We discuss the results of Monte Carlo simulations on a model that seems to have the necessary ingredients to describe this state, in two, three and four dimensions. The technique involves computing the free ener...
متن کاملVortex glass transition in a random pinning model.
We study the vortex glass transition in disordered high temperature superconductors using Monte Carlo simulations. We use a random pinning model with strong point-correlated quenched disorder, a net applied magnetic field, long-range vortex interactions, and periodic boundary conditions. From a finite size scaling study of the helicity modulus, the rms current, and the resistivity, we obtain cr...
متن کاملUniversal Susceptibility Variations in 1+1 Dimensional Vortex Glass
We model a planar array of fluxlines as a discrete solid-on-solid model with quenched disorder. Simulations at finite temperatures are made possible by a new algorithm which circumvents the slow glassy dynamics encountered by traditional Metropolis Monte Carlo algorithms. Numerical results on magnetic susceptibility variations support analytic predictions.
متن کاملUnified phase diagram for the three-dimensional XY model of a point-disordered type-II superconductor
We carry out extensive Monte Carlo simulations of the three-dimensional uniformly frustrated XY model with uncorrelated randomly perturbed couplings, as a model for the equilibrium behavior of an extreme type-II superconductor with quenched uncorrelated random point vortex pinning, in the presence of a uniform applied magnetic field. We map out the resulting phase diagram as a function of tempe...
