之后,他在这一领域不断刷新纪录。
2017年,其团队设计的新型原子钟,将锶原子装入微小的三维立方体中,密度较以前一维原子钟设计中锶原子的密度高出近1000倍,进一步提升原子钟测量精度。
2020年,叶军团队曾在3天内连发Nature、Science论文。
发表在Nature上的《Dipolar evaporation of reactive molecules to below the Fermi temperature》中,其团队首次实现量子简并气体。
另一篇发表在Science的论文《Resonant collisional shielding of reactive molecules using electric fields》,则用量子力学理论解释了分子间的碰撞。
