Attosecond charge migration in a neutral molecule has been observed to decohere within approximately 10 fs. However, this does not mean that the electronic coherence is irreversibly lost, as the charge migration is observed to revive after 40–50 fs. These findings have the potential to enable laser control of photochemical processes.

观察核运动对阿秒电荷迁移的影响

已观察到中性分子中的阿秒电荷迁移在大约 10 fs 内退相干。然而，这并不意味着电子相干性不可逆地丧失，因为观察到电荷迁移在 40-50 fs 后恢复。这些发现有可能使激光控制光化学过程。
