代表性工作:

热里德堡气体中自感应透明效应研究：

自感应透明效应是光与物质相干共振耦合产生的瞬态强非线性光学效应，脉冲面积为2π的光场可以无形变地在原子气体中传输。我们提出了利用自感应透明效应，实现了纳秒脉冲激光在室温里德堡原子气体中稳定传输的具体理论方案，并证明了里德堡多体系统可以得到新的、与原子相互作用有关的脉冲传播面积定理，该工作发表在Phys. Rev. Lett.125.263605 (2020).

超冷里德堡气体中光子弹传输特性研究：

自然界中时间与空间都保持高度局域的光束是很难存在的，光场的色散与衍射往往是不可避免。近期研究表明，里德堡电磁诱导透明系统中同时存在两种不同类型的克尔非线性，它们之间既有相互合作又有相互竞争，选取适当的物理参数，可使系统内诸多物理效应达到平衡，并得到了稳定传播的 (3+1) 维超慢弱光子弹，该工作发表在Optica 6 , 309 (2019).

辅助激发诱导透明与单光子动力学开关

通过数值模拟以及解析证明，发现了辅助激发诱导透明 (FIT) 的新奇物理现象。不同于电磁诱导透明机制，FIT是由于原子相互作用引起的多体量子干涉效应，可非破坏探测多体系统的强关联特性。利用FIT机制，可设计了无接触的动力学单光子开关，该开关具有相干保护的重要特性，该工作发表在Phys. Rev. Applied 19 , 014017 (2023).
