相敏实验告诉我们什么？
What do the phase-sensitive experiments tell us?
摘要：
铜氧化物超导体的相敏实验告诉我们凝聚态波函数的对称性。但是，他们不能确定库珀对的对称性。为了描述超导态，需要两个波函数，凝聚波函数和配对波函数。前者描述了电子对的整体运动，后者描述了一对电子中两个电子的相对运动。在相敏约瑟夫森测量中观察到的$π$相移不能证明对态是d波。我们在这里提出一个新的解释，并预测一些新的可观察到的现象。
英文摘要：
The phase-sensitive experiments on cuprate superconductors have told us about the symmetry of the condensate wavefunction. However, they can not determine the pairing symmetry of Cooper pairs. To describe a superconducting state, two wavefunctions are needed, condensate wavefunction and pairing wavefunction. The former describes the entirety movement of the pairs and the latter describes the relative movement of the two electrons within a pair. The $π$-phase shift observed in the phase sensitive Josephson measurements can not prove that the pairing state is d-wave. We present here a new explanation and predict some new observable phenomena.
