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年中，我们开发了两个用于强光物质相互作用的数值代码。这两种代码都是破坏性的，因为它们允许研究光物质相互作用的物理和化学领域，而这些领域是任何其他现有工具都无法模拟的。目前的研究计划建立在过去5年的开发工作的基础上。数值代码将应用于强场激光物理的各个领域的分析，如：电介质的微纳米加工，x射线自由电子激光器的单分子成像，强耦合等离子体动力学和恒星物理，阿秒科学，以及激光驱动原子和分子的相关动力学。由于我们有幸拥有新的理论工具，我们期望所提出的研究将产生重大影响。所有这些子项目背后的主要愿景如下。我们希望找到在空间和时间上分辨自然界中超快和超细过程的方法。与地球上的生命有关的最快和最好的机制是电子过程。它们在自然界的各个方面都发挥着重要的作用，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它们的电子动力学来制作这些过程的电影。
