物理系colloquium：Strong correlations meet electron-phonon coupling

报告题目：Strong correlations meet electron-phonon coupling报告人：王强华南京大学报告地点：理学院郑裕彤大讲堂报告时间：2024年9月26日16:00报告摘要：In this talk, I discuss several remarkable effects when strong electron correlations coexist with electron-phonon coupling. In high-Tc cuprates, the isotope exponent diminishes around optimum doping, but the exponent diverges positively in underdo...

中子寿命疑难以及一种基于立方星的新方案

报告题目：中子寿命疑难以及一种基于立方星的新方案报告人：孙保华，北京航空航天大学报告时间：2024年9月18日 (周三) 15:00报告地点：物理楼W260报告摘要：中子是组成原子核的两种组分之一，但却几乎不存在脱离原子核而单独存在的中子，这是因为自由的中子会在15分钟左右发生衰变。中子的寿命直接关联着对物质结构和宇宙演化的理解。实验上研究中子寿命主要有“瓶实验”和“束实验”，经过数十年的努力，两种方法的精度均已...
