电子间的关联体现在从同一个原子电离出来的两个光电子倾向于以相同速度沿场的同一方向发射,从而在动量关联谱中聚集出两个鸡蛋形的亮斑.随着实验精度的提高,发现动量关联谱实际上表现为finger结构,其物理机制不清楚.北京大学应用物理与技术研究中心刘杰与合作者发展了一套半经典模型,巧妙地将量子隧穿和经典再散 The correlation between electrons is that the two photoelectrons that ionize from the same atom tend to emit in the same direction along the field at the same speed, thus gathering two egg-shaped bright spots in the momentum correlation spectrum. As experimental accuracy increases And found that the momentum correlation spectrum actually behaves as a finger structure and its physical mechanism is unclear.Liu Jie and Peking University applied physics and technology research center developed a set of semi-classical models, cleverly quantum tunneling and classical re-loose
