Abstract. We carry out a systematic analytic investigation of stationary and cylindrically symmetric vortex configurations for simple models representing an incompressible non-relativistic superconductor in a background, which is rigidly rotating with the angular velocity Ω∞. It is shown that although the magnetic and kinetic contributions to the energy per unit length of such a vortex are sepa...

The effect of smooth inhomogeneities near a superconductor boundary on the magnetic penetration depth λ is studied with emphasis on the proximity-induced spatial dependence of the Cooper pair amplitude. The influence of surface pair breaking or pair formation on λ is described within the Ginzburg-Landau theory, with no model assumptions, for both strongly type-II and strongly type-I homogeneous...

We obtain an effective string theory of the Abrikosov–Nielsen–Olesen vortices of the Abelian Higgs model. The theory has an anomaly free effective string action which, when the extrinsic curvature is set equal to zero, yields the Nambu–Goto action. This generalizes previous work in which a string representation was obtained in the London limit, where the magnitude of the Higgs field is fixed. V...

Static vortices close together are studied for two different models in 2-dimensional Euclidean space. In a simple model for one complex field an expansion in the parameters describing the relative position of two vortices can be given in terms of trigonometric and exponential functions. The results are then compared to those of the Ginzburg-Landau theory of a superconductor in a magnetic field ...

We report muon-spin-relaxation studies in weak transverse fields of the superconductivity in the metal cluster compound, Ga84[N(SiMe3)2]20-Li6Br2(thf)20.2 toluene. The temperature and field dependence of the muon-spin-relaxation rate and Knight shift clearly evidence type II bulk superconductivity below Tc approximately 7.8 K, with Bc1 approximately 0.06 T, Bc2 approximately 0.26 T, kappa appro...

The new type of solutions of the London equation for type-II superconductors is obtained to describe the ring-shaped (toroidal) Abrikosov vortices. The specific feature of these solutions is the self-consistent localization of both the supercurrent and the magnetic field, enabling one to construct compact magnetic structures inside a superconductor. The torus vortex contraction caused by the vo...

background: diabetic nephropathy is considered to be the most common cause of end stage renal disease (esrd). proteinuria is declared as the most marked risk factor in progression towards esrd. the aim of this study was to evaluate the efficacy of pentoxifylline for reduction of proteinuria in type ii diabetic patients. methods: from may 2007 to june 2008, this randomized clinical trial study w...

One-dimensional systems proximity-coupled to a superconductor can be driven into topological superconducting phase by an external magnetic field. Here, we investigate the effect of vortices created field in type-II providing proximity effect. We identify different ways which protection Majorana modes compromised and discuss strategies circumvent these detrimental effects. Our findings are also ...
