One of the outstanding problems in contemporary solid state physics concerns the mechanism of high temperature superconductivity (HTS). In particular, what binds charges that normally repel one another, into (Cooper) pairs? Closely related to this question is where the superconductivity resides in the material. We aim to answer the latter question in the much studied prototypical HTS YBa2Cu3O7. In doing so we expect to demonstrate that phonons, widely believed not to play a role in HTS are in fact an important component in the HTS pairing mechanism.

高温超导的机理是当代固体物理学中的一个突出问题。特别是，是什么将通常相互排斥的电荷结合成（库珀）对？与这个问题密切相关的是超导性在材料中的位置。我们的目标是在经过大量研究的HTS YBa2Cu3O7原型中回答后一个问题。在这样做的过程中，我们期望证明声子，普遍认为在高温超导中不起作用，实际上是高温超导配对机制的重要组成部分。
