Numerical calculation of the vortex–columnar-defect interaction and critical currents in extreme type-II superconductors—a two-dimensional model based on the Ginzburg–Landau approximation
We extend our previous one-dimensional Ginzburg–Landau calculations of the pinning energy of vortices to two dimensions, in order to achieve an understanding of the pinning forces exerted on vortices by defects. By minimizing the free energy using a relaxation scheme, we obtain the spatial variation of the order parameter and supercurrents for a vortex in the vicinity of a cylindrical defect in...
متن کاملLocalized Flux Lines and the Bose Glass
Columnar defects provide effective pinning centers for magnetic flux lines in high–Tc superconductors. Utilizing a mapping of the statistical mechanics of directed lines to the quantum mechanics of two–dimensional bosons, one expects an entangled flux liquid phase at high temperatures, separated by a second–order localization transition from a low–temperature “Bose glass” phase with infinite ti...
متن کاملField-induced quasiparticle excitations in novel type II superconductors
We show that the field dependence of the magnetic penetration depth (λ), for which muon spin rotation (μSR) is an excellent microscopic probe, provides useful information on the degree of anisotropy for the superconducting order parameter. In type II superconductors associated with anisotropic order parameters, λ is sensitive to the quasiparticle excitation induced by the Doppler shift due to a...
متن کاملTopological defects in the random-field XY model and the pinned vortex lattice to vortex glass transition in type-II superconductors.
As a simplified model of randomly pinned vortex lattices or charge-density waves, we study the random-field XY model on square (d = 2) and simple cubic (d = 3) lattices. We verify in Monte Carlo simulations, that the average spacing between topological defects (vortices) diverges more strongly than the Imry-Ma pinning length as the random field strength, H, is reduced. We suggest that for d = 3...
متن کاملMaximum Entropy Distributions Describing Critical Currents in Superconductors
Maximum entropy inference can be used to find equations for the critical currents (Jc) in a type II superconductor as a function of temperature, applied magnetic field, and angle of the applied field, θ or . This approach provides an understanding of how the macroscopic critical currents arise from averaging over different sources of vortex pinning. The dependence of critical currents on tempe...
