关于三维Ginzburg-Landau临界场

On the Ginzburg-Landau critical field in three dimensions

S. Fournais, B. Helffer

摘要:

本文研究了三维Ginzburg-Landau超导模型。几个“自然”的定义(第三)临界场,$H_{C_3}$,管理从超导状态到正常状态的过渡,被认为是。我们分析了这些领域之间的关系,并给出了条件,当他们重合。分析的一个有趣的部分是拉普拉斯算子的基态能量的单调性的研究,与恒定磁场和Neumann(磁)边界条件,在域$Ω$。证明了当电场足够大时,基态能量是场强的严格增函数。由于我们的分析,我们给一个肯定的答案,潘猜想。

英文摘要:

We study the three dimensional Ginzburg-Landau model of superconductivity. Several `natural' definitions of the (third) critical field, $H_{C_3}$, governing the transition from the superconducting state to the normal state, are considered. We analyze the relation between these fields and give conditions as to when they coincide. An interesting part of the analysis is the study of the monotonicity of the ground state energy of the Laplacian, with constant magnetic field and with Neumann (magnetic) boundary condition, in a domain $Ω$. It is proved that the ground state energy is a strictly increasing function of the field strength for sufficiently large fields. As a consequence of our analysis we give an affirmative answer to a conjecture by Pan.
