Dynamics of complex systems in intense fields

在过去的5年里，我们已经开发了两个用于强烈光物质相互作用的数值代码。这两个代码都具有颠覆性，因为它们允许研究轻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无法模拟的。 目前的研究提案建立在过去5年所做的开发工作的基础上。这些数值代码将应用于强场激光物理的各个领域的分析，如：电介质的微纳加工，X射线自由电子激光的单分子成像，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关联动力学。由于我们有幸掌握了新的理论工具，我们预计拟议中的研究将产生重大影响。 所有多种多样的子项目的主要愿景如下。我们想要确定在空间和时间上分辨自然界中的超快和超精细过程的方法。地球上与生命相关的最快、最精细的机制是电子过程。它们在自然界的方方面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方面。最终的梦想将是通过在空间和时间上解析这些过程的电子动力学来拍摄电影。

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.
