RUI: Spatial and Temporal Dynamics of Matter in Intense Laser Fields

这项工作的目的是在计算机模拟的帮助下更好地理解物质与激光脉冲的相互作用。这些项目关注的是，如果激光足够强，能够在真空中触发粒子-反粒子对的产生，就会出现新的现象，并研究光子作为原子中力介质的基本作用。这项工作是基于量子电动力学的一种新方法，目标是操纵和控制高能粒子之间的相互作用。激光控制物质产生过程新时代的跨学科特性有望在原子、核、等离子体和激光物理之间提供新的联系。由于研究过程的基本性质，进展可以推进其他领域，如基于加速器的明亮光源的发展，提供在很短的时间尺度上控制原子、化学和生物过程的新方法。基于可视化的计算量子场论方法将有助于解决概念上的争议，同时提供更直观和更少抽象的方法来学习和教授相对论量子力学。一项重要的任务是让本科生从大一开始就有机会获得个人研究经验。这种教育经历为他们提供了重要的技能，包括团队合作，获得耐力，智力灵活性和解决重大研究问题的经验，以及在会议和出版物中传达结果。

The work aims at providing a better understanding of the interaction of matter with laser pulses with the aid of computer simulations. The projects focus on new phenomena that occur if lasers are sufficiently intense to trigger the creation of particle-antiparticle pairs from the vacuum and examine the fundamental role of photons as mediators of forces in atoms. The work is based on a new approach to quantum electrodynamics with the goal to manipulate and control interactions between energetic particles. The interdisciplinary character of the new era of laser controlled matter creation processes is expected to provide new connections between atomic, nuclear, plasma and laser physics. Due to the fundamental nature of the processes examined, progress could advance other areas such as the development of accelerator-based bright light sources, providing new ways to control atomic, chemical and biological processes on very short time scales.The visualization-based approach to computational quantum field theory will help to resolve conceptual controversies while providing more intuitive and less abstract ways to learn and teach relativistic quantum mechanics. An important mission is to give undergraduate students, starting in their freshman year, the opportunity to gain personal research experience. This educational experience provides them with important skills including working as a team, gaining the endurance, intellectual flexibility and experience to tackle serious research problems, and communicating results in conferences and publications.
