Harnessing Electron Dynamics: Attosecond and Nanometer Scale Control and Observation

April 29, 2024
California NanoSystems Institute
Alfred E Mann Family Foundation Auditorium
12:30 – 1:30 PM PT

Attosecond science, which garnered the 2023 Nobel Prize in Physics, offers unprecedented insights into electron dynamics by allowing for the control and observation of electrons on their intrinsic time and spatial scales. This field underpins advancements in lightwave electronics by facilitating the manipulation of solid-state responses to intense optical frequency light, achieving current switching at petahertz scales. Such capabilities represent the zenith of electronic speed, approaching the limits imposed by the speed of light. In this presentation, I will elucidate the principles of attosecond science and lightwave electronics, and highlight our recent contributions. These include controlled electron emission and currents, precise sampling of light fields, and the implementation of a lightwave-driven Haldane model in two-dimensional materials (figure). Additionally, I will discuss the transformative impact of free- electron lasers that produce intense attosecond pulses across soft and hard X-ray spectra, with the Linac Coherent Light Source (LCLS) at the forefront. The recent commencement of its superconducting accelerator, which delivers X-ray pulses at megahertz frequencies, marks a significant milestone. I will explore these developments and the vast scientific possibilities they usher in at LCLS.
