We present a study on the dissociation of a weakly bound molecular ion in the presence of an external time-dependent electric field based on a full quantum treatment of the dynamics. We focus on the dissociation dynamics of a molecular ion in a Paul trap relevant for atom-ion hybrid traps. Our results show that a weakly bound molecular ion survives in a Paul trap giving a theoretical ground to previous experimental findings [A. Krükow et al. Phys. Rev. Lett. 116, 193201 (2016) and A. Mohammadi et al., Phys. Rev. Research 3, 013196 (2021)]. In particular, we find that weakly bound molecular ions are more likely to survive in traps with a large rf frequency. Similarly, we show that applying an electric field ramp is an efficient method to state-selectively detect weakly bound molecular ions, analogous to the well-known selective field ionization technique applied in Rydberg atoms.

弱结合分子离子的电场解离

我们基于动力学的全量子处理，在存在外部时间相关电场的情况下，对弱结合分子离子的解离进行了研究。我们专注于与原子 - 离子混合陷阱相关的保罗陷阱中分子离子的解离动力学。我们的结果表明，弱结合的分子离子在 Paul 阱中存活，为之前的实验结果提供了理论依据 [A. Krükow等人。 物理。牧师莱特。 116 , 193201 (2016) 和 A. Mohammadi等。，物理。修订版研究 3, 013196 (2021)]。特别是，我们发现弱结合的分子离子更有可能在具有大 rf 频率的陷阱中存活。同样，我们表明应用电场斜坡是一种有效的方法来状态选择性地检测弱结合的分子离子，类似于在里德堡原子中应用的众所周知的选择性场电离技术。
