Abstract

We provide a brief review of how phase space techniques are explored within strong-field and attosecond science. This includes a broad overview of the existing landscape, with focus on strong-field ionisation and rescattering, high-order harmonic generation, stabilisation and free-electron lasers. Furthermore, using our work on the subject, which deals with ionisation dynamics in atoms and diatomic molecules as well as high-order harmonic generation in inhomogeneous fields, we exemplify how such tools can be employed. One may for instance determine qualitatively different phase space dynamics, explore how bifurcations influence ionisation and high-harmonic generation, establish for which regimes classical and quantum correspondence works or fails, and what role different timescales play. Finally, we conclude the review highlighting the importance of the tools available in quantum optics, quantum information and physical chemistry to strong-field laser–matter interaction.

相空间中的生命科学

摘要

我们简要回顾了如何在强场和阿秒科学中探索相空间技术。这包括对现有景观的广泛概述，重点是强场电离和再散射、高次谐波产生、稳定和自由电子激光器。此外，利用我们在该主题上的工作，该主题涉及原子和双原子分子中的电离动力学以及非均匀场中的高次谐波生成，我们举例说明了如何使用这些工具。例如，可以确定性质不同的相空间动力学，探索分岔如何影响电离和高次谐波的产生，确定经典和量子对应对哪些机制有效或失败，以及不同时间尺度所起的作用。最后，
