【中央研究院全球顶尖人物系列演讲】 Prof. Anthony J. Leggett (2003年诺贝尔物理奖得主) 时间：2009年1月6日 下午2点20分 地点：台湾大学物理系新馆 R204 国际会议厅 讲题：Cuprate superconductivity without a ‘model' 摘要： I start by reviewing the question: What can we reasonably say we know _for sure_ about superconductivity in the cuprates, without reliance on any microscopic "model"? Then I ask: On the basis of this knowledge and of some very generic and hopefully reasonable assumptions, are there interesting questions we can ask which we have some hope of answering definitively by experiment? I identify one such question, namely: In whcih regions of momentum and frequency space is the inter-conduction electron Coulomb interaction energy saved (or expended) when the system becomes superconducting? I conjecture a possible answer to this question, show that it is consistent with the dependence of the transition temperature on the c-axis layering structure and emphasize that it makes _quantitative and experimentally testable predictions. 这种机会可不常有， 冲一发啊！ -- 您知道吗？ 期末考差不多该开始念了。 --
