迈斯纳效应与贝克尔-伦敦效应的动力学研究

On the dynamics of the Meissner and the Becker-London effects

Peter Markoš, Richard Hlubina

AI总结:

针对传统超导理论未探讨迈斯纳效应与贝克尔-伦敦效应动态产生机制的问题,本文结合伦敦方程求解麦克斯韦方程组,研究两种效应的电磁场演化,证明传统理论可正确描述其动力学,填补了文献空白。

摘要:

通常认为超导体最基本的性质是展现迈斯纳效应。同等重要的是贝克尔-伦敦效应,即旋转超导体内部产生磁场。Hirsch最近指出,在传统超导理论中,关于这些效应如何动态产生的问题甚至尚未被提出。本文通过详细研究这两种效应的电磁场演化来填补文献中的这一空白。为此,我们求解了麦克斯韦方程组,并补充了超导体最简单的传统本构方程——伦敦方程。我们证明,与Hirsch的预期相反,传统理论确实能正确描述迈斯纳效应和贝克尔-伦敦效应的动力学。我们发现,即使在这种描述水平下,所研究过程的动力学也相当丰富有趣。

英文摘要:

It is generally accepted that the most fundamental property of a superconductor is that it exhibits the Meissner effect. Of similar importance is the Becker-London effect, i.e. generation of magnetic field inside a rotating superconductor. Hirsch has recently pointed out that, within the conventional theory of superconductivity, the question about how these effects are generated dynamically has not even been asked yet. Here we fill in this gap in the literature by a detailed study of the evolution of the electromagnetic field for both of these effects. To this end, we solve the Maxwell equations supplemented by the simplest conventional constitutive equation for a superconductor, namely the London equation. We demonstrate that, contrary to the expectations of Hirsch, the conventional theory does correctly describe the dynamics of both, the Meissner and the Becker-London effect. We find that the dynamics of the studied processes is quite rich and interesting even at this level of description.
