标题： Annular Vortex Solutions to the Landau-Ginzburg Equations in Mesoscopic Superconductors

摘要： 描述了Landau-Ginzburg方程的新涡旋解。 这些构型扩展了众所周知的Abrikosov涡旋和大磁涡旋，由一系列环状超电流涡旋组成，以同心模式排列，可能与一个位于其中心的大磁涡旋结合。 这些环形涡旋的动力学和热力学稳定性是一个重要的开放问题，直接实验观察这些构型取决于此。 然而，环形涡旋应间接影响可进行物理观测的介观超导器件的特定动态特性。 显示英文摘要

摘要： New vortex solutions to the Landau-Ginzburg equations are described. These configurations, which extend the well known Abrikosov and giant magnetic vortex ones, consist of a succession of ring-like supercurrent vortices organised in a concentric pattern, possibly bound to a giant magnetic vortex then lying at their center. The dynamical and thermodynamic stability of these annular vortices is an important open issue on which hinges the direct experimental observation of such configurations. Nevertheless, annular vortices should affect indirectly specific dynamic properties of mesoscopic superconducting devices amenable to physical observation.
