Electrons emit light, carry electric current, and bind atoms together to form molecules. Insight into their atomic-scale motion is the key to understanding the functioning of biological systems, developing efficient sources of x-ray light, and speeding up electronics. Capturing this electron motion requires attosecond (one quintillionth of a second) time resolution. Our research aims to understand and accurately model fundamental atomic processes taking place on the attosecond time scale. This research project will further enhance our reputation in an area where Australian theorists are preeminent, and the research training will produce PhD graduates with the skills essential in a multitude of nano-technology applications.

电子发出光，携带电流，并将原子结合在一起形成分子。深入了解它们的原子尺度运动是理解生物系统功能、开发有效的x射线光源和加速电子技术的关键。捕捉这种电子运动需要阿秒（五分之一秒）的时间分辨率。我们的研究旨在理解和准确地模拟在阿秒时间尺度上发生的基本原子过程。该研究项目将进一步提高我们在澳大利亚理论家卓越的领域的声誉，研究培训将培养具有众多纳米技术应用所需技能的博士毕业生。
