This research addresses the question of atoms interacting with light in a radically nonperturbative, ultrahigh laser intensity range from 1017 W/cm2 to 1019 W/cm2. The science has direct bearing on a number of topics, including new multi-electron phenomena, nonperturbative magnetic field-atom interactions, relativistic continuum dynamics, the breakdown of the semiclassical WKB approximation in strong field physics, and high-energy radiation from laser-atom interactions. The atomic physics and laser technology in the proposal has a direct impact on fourth generation XUV and X-ray radiation light sources, with applications as wide-ranging as device lithography and single molecule x-ray diffraction. The education component of the proposal is directed toward high-school and college student perceptions of physics and addresses the new pedagogy behind real-world, electronic teaching resources.

这项研究解决了原子与光相互作用的问题，从1017 W/cm ~ 2到1019 W/cm ~ 2的激光强度范围内完全无微扰。 这门科学直接关系到许多主题，包括新的多电子现象，非微扰磁场-原子相互作用，相对论连续动力学，强场物理中半经典WKB近似的崩溃，以及激光-原子相互作用的高能辐射。 该提案中的原子物理和激光技术对第四代XUV和X射线辐射光源产生了直接影响，其应用范围广泛，如设备光刻和单分子X射线衍射。 该提案的教育部分是针对高中和大学生对物理的看法，并解决了现实世界，电子教学资源背后的新教学法。
