# Attoclock revisited on electron tunnelling time

## TL;DR

This paper reviews recent advances in understanding electron tunnelling time, analyzing the attoclock experiment and concluding that models with finite tunnelling time align with experimental data.

## Contribution

It provides a comprehensive review of recent theoretical and experimental developments in tunnelling time and reinterprets the attoclock experiment with models including finite tunnelling time.

## Key findings

- Models with finite tunnelling time agree with recent measurements
- Reinterpretation of the attoclock experiment supports finite tunnelling time
- Recent developments clarify the tunnelling time debate

## Abstract

The last decade has seen an intense renewed debate on tunnelling time, both from a theoretical and an experimental perspective. Here, we review recent developments and new insights in the field of strong-field tunnel ionization related to tunnelling time, and apply these findings to the interpretation of the attoclock experiment [Landsman et al., Optica 1, 343 (2014)]. We conclude that models including finite tunnelling time are consistent with recent experimental measurements.
