The debate on tunnelling times have always been full of contradictions and the attoclock experiments that measure tunnelling delays in strong-field ionization are no exception. The current review presents the debate and discussions concerning the studies of tunnelling times based only on the attoclock technique. We review them with their implications and pitfalls identified due to lack of accurate strong field models that validate the observations in interpreting the measurements performed on noble gases. In order to provide a complete picture, the review begins with a background on some of the popular tunnelling time definitions, most of them conceived during the late 1980s debate, which are often cited in the attoclock literature. We then discuss various attoclock experiments on noble gas atoms and their interpretations in context of the tunneling time debate. The recently performed attoclock experiment and numerical modelling using atomic hydrogen are also presented as an att...

Attoclock和对强场物理学中隧道时间的追求

关于隧穿时间的争论始终充满矛盾，测量强场电离中的隧穿延迟的原子钟实验也不例外。本篇综述提出了仅基于钟表技术的有关隧道时间研究的辩论和讨论。由于缺乏准确的强场模型，这些研究的含义和隐患使我们对其进行了审查，这些模型验证了解释稀有气体测量结果时的观察结果。为了提供一个完整的图景，本文以一些流行的隧道时间定义为背景，这些定义大多数是在1980年代后期的辩论中提出的，并且经常在attoclock文献中引用。然后，我们将在隧道时间辩论的背景下讨论各种关于惰性气体原子的常时实验及其解释。最近还进行了一次使用原子氢的原子钟实验和数值模拟，以此作为实验的参考。
