Recent c axis-polarized infrared measurements in the high-transition temperature (high-T(c)) cuprate superconductor (La,Sr)(2)CuO(4) can be interpreted on the basis that the entire condensation energy comes from the interlayer Josephson coupling. This gives a parameter-free determination of penetration depth lambda and coherence length xi for this superconductor that are in agreement with experiment.
最近在高温超导（high-T(c)） cuprate 超导体（La,Sr）(2)CuO(4) 中进行的 c 轴极化红外测量，可以基于以下观点进行解释：即整个凝聚能来自于层间约瑟夫森耦合。这为该超导体的穿透深度 lambda 和相干长度 xi 提供了无参数的确定，与实验结果一致。
