Over the past 5 years we have developed two numerical codes for intense light matter interaction. Both codes are disruptive in the sense that they allow the investigation of areas of light matter interaction physics and chemistry that cannot be modelled by any other existing tools. The current research proposal builds on the development work done over the past 5 years. The numerical codes will be applied to the analysis of various areas of strong field laser physics, such as: micro- and nano-machining of dielectrics, single molecule imaging with x-ray free electron lasers, strongly coupled plasma dynamics and the physics of stars, attosecond science, and correlated dynamics in laser driven atoms and molecules. Due to our fortunate position of having new theoretical tools at our disposal, we expect that the proposed research will make a major impact. The main vision that underlies all the manifold sub-projects is the following. We would like to identify methods for spatially and temporally resolving ultrafast and ultrafine processes in nature. The fastest and finest mechanisms relevant to life on earth are electronic processes. They play an important role in all aspects of nature, such as for example in the making and breaking of molecular bonds and in the dynamics of solids and plasmas. The ultimate dream would be to make movies of these processes by spatially and temporally resolving their electronic dynamics.

在过去的5年里，我们已经开发了两个数值代码的强光物质相互作用。这两个代码都是破坏性的，因为它们允许对光物质相互作用物理和化学领域进行调查，而这些领域无法通过任何其他现有工具进行建模。目前的研究提案是在过去5年所做的开发工作的基础上提出的。数值代码将被应用于强场激光物理学的各个领域的分析，如：微纳米加工的激光器，单分子成像与X射线自由电子激光器，强耦合等离子体动力学和恒星物理学，阿秒科学，激光驱动的原子和分子的相关动力学。由于我们幸运地拥有新的理论工具，我们希望拟议的研究将产生重大影响。所有多个次级项目的主要设想如下。我们希望找出在空间和时间上分辨自然界中超快和超细过程的方法。与地球上的生命相关的最快和最精细的机制是电子过程。它们在自然界的各个方面都发挥着重要作用，例如在分子键的形成和断裂以及固体和等离子体的动力学中。最终的梦想是通过在空间和时间上解析这些过程的电子动力学来制作这些过程的电影。
