I analyze the low temperature limit of the BCS theory of s-wave single-band superconductors, when the attraction band (defined as the single-particle energy interval in which the pairing interaction is manifested) may be asymmetric with respect to the chemical potential. I discuss equilibrium ...
很久没上知乎,这几天阅读Ginzberg的文章"Experimental Foundations of the BCS Theory of Superconductivity",为学校的超导物理讨论班介绍一些实验内容,在这里简单做个chronological的记录。 Before BCS 1. 电磁性质 1908年由Onnes于Leiden实验室实现氦的液化,标志着低温物理进入4.2K以下的温区。Onnes主要用的技术是Linde于...

这一切开始于1948年的一篇论文——《论超导的分子理论问题》(On the Problem of the Molecular Theory of Superconductivity)。弗里茨·伦敦在这篇文章中提出,伦敦方程可能是量子态相干性的结果。1953年,皮帕德(Brian Pippard)提出相干长度的概念,对伦敦方程作了非局域的推广。然后,巴丁在1955年发表的论文《超导...
Note: The theory was first described by the three physicists as "Microscopic Theory of Superconductivity," in the "Letters to the Editor" section of Physical Review, vol. 106, Issue 1 (April, 1957), pp. 162-64. First Known Use 1958, in the meaning defined above Time Traveler The first...
英语中的缩写词“BCS”代表了“Bardeen Cooper Schrieffer theory of superconductivity”,简称“巴丁库珀-施里弗超导理论”。这个理论在物理学领域具有重要地位,其缩写词在学术界尤其常见,流行度达到了1797次。BCS主要应用于超导现象的研究,解释了低温下电子如何协同运动,形成无电阻的超导状态。BCS的中文...
很久没上知乎,这几天阅读Ginzberg的文章"Experimental Foundations of the BCS Theory of Superconductivity",为学校的超导物理讨论班介绍一些实验内容,在这里简单做个chronological的记录。在电磁性质方面,研究者们在远红外吸收光谱中观测到了特定的模式,这是BCS理论预测的结果。Glover和Tinkham在1958年的...
在同年12月的文章《超导理论》(Theory of superconductivity)中,他们证明,超导相变是二级相变,他们的理论可以解释同位素效应和迈斯纳效应,以及为什么超导态只能发生在绝对零度附近——在大量的热扰动下,脆弱的库珀对会断裂。此外,他们还给出了关于比热和电磁...
The BCS theory of superconductivity developed in 1957 by Bardeen, Cooper and Schrieffer has been remarkably successful in explaining the properties of superconductors. In addition, concepts from BCS have been incorporated into diverse fields of physics, from nuclear physics and dense quark matter to th...
