Abstract

We derive an exact passage for atom-trimer conversion via the resonance-locked inverse engineering. In particular, the temporal shapes of the fields and the detunings correspond to the exact solution of the system. As a result, the atoms can be perfectly converted into trimers when we choose the suitable parametrization, in which the conversion rate is close to 100%. Compared to the nonlinear stimulated Raman adiabatic passage, the conversion process for exact passage is more robust and faster, which does not be affected by three-body interactions.

通过共振锁定逆工程实现原子-单核-三聚体的稳定转换

我们通过共振锁定逆工程推导出原子-三聚体转换的精确通道。特别是，场的时间形状和失谐与系统的精确解相对应。因此，当我们选择合适的参数时，原子可以完美地转换成三聚体，转换率接近 100%。与非线性受激拉曼绝热通过相比，精确通过的转换过程更稳健、更快速，不受三体相互作用的影响。
