# Probing Attosecond Photoionization Dynamics and Charge Migration

> **NSF 01002526DB NSF RESEARCH & RELATED ACTIVIT** · Arizona State University (AZ) · $469,998

## Abstract

Advances in laser and x-ray technology have enabled scientists to study quantum processes in atoms, molecules, and materials with unprecedented time resolution. This project will apply x-ray pulses that are shorter in duration than a millionth of a billionth of a second to investigate a fundamental question in quantum physics: how fast is the electron ejected from a molecule hit by a light pulse? The awardee will study the timescale of the electron ejection, and its dependence on the molecular environment. The research team funded by this award will use ultrafast measurements to understand how electrons interact with each other, and how the light-molecule interaction is impacted by the positions of atoms within the molecule. The knowledge gained from this research will facilitate strategies for controlling the flow of charge and energy inside molecules for practical applications in the fields of light harvesting and energy storage. Additionally, it will enhance our understanding of the electronic processes behind DNA damage and vitamin D synthesis, and contribute to the development of ultrafast quantum devices for national security applications. The students engaged in this project will gain cutting-edge technical expertise in ultrafast science and develop scientific proficiency to initiate their own research investigations. This will foster scientific innovation and enhance the competitiveness of our nation in critical research areas.
