报告摘要：
超导物理的研究发展，二十多年前铜氧化物高温超导体的发现，是科学史上少见、令人惊奇的事件。此发现对科学界的影响，至今仍保持在高峰状态。目前超导体研究最主要的材料可归类成两大系统，一种以铜金属为主体、另一类则以铁金属为主。我们最近在铁硒超导研究的成果得到一个很明确的结论，铁硒材料存在有铁空位是形成其超导性的先驱条件，当这些铁空位的排列无序化后，超导就出现，此现象与老子所述「有」「无」间之关联的概念相通。这样的结论是否可以推广到铜氧气化物超导体，是我们目前研究探索的另一主题。最近杨振宁先生在「美与物理学」的演讲中，提到许多重要物理现象来自对称破缺(Symmetry Breaking)。杨先生由这些现象，推测物理学目前所建构的基础理论，仍有些欠缺，需要更深一层的理论架构。高温超导的问题，以目前的实验结果来看，材料本质上都存在某种程度的缺限，或许也需要类似的理论架构，才能完整理解高温超导形成的机制，这或许是我们下一步需要深究的主要课题。
