三维超导中Ginzburg-Landau泛函的收敛性

Sisto Baldo, Robert L. Jerrard, Giandomenico Orlandi, Mete Soner

摘要:

本文研究了三维超导Ginzburg-Landau模型在不同能量下的渐近行为。本文通过Γ-收敛分析,严格地导出了涡旋密度的简化模型,并导出了涡旋线的曲率方程。在配套文件中,我们描述了进一步的应用超导性和超流性,如第一临界磁场H_{c1}的一般表达式,旋转玻色-爱因斯坦凝聚体的临界角速度。

英文摘要:

In this paper we consider the asymptotic behavior of the Ginzburg- Landau model for superconductivity in 3-d, in various energy regimes. We rigorously derive, through an analysis via Γ-convergence, a reduced model for the vortex density, and we deduce a curvature equation for the vortex lines. In a companion paper, we describe further applications to superconductivity and superfluidity, such as general expressions for the first critical magnetic field H_{c1}, and the critical angular velocity of rotating Bose-Einstein condensates.
