Physics Colloquium: “Emerging Frontiers at the Intersection between Photon Sciences, Molecular Dynamics, and Light-Matter Interactions”

Abstract: Photon and particle sources are powerful tools with extremely high societal impact because they underpin myriad groundbreaking scientific, technological, and medical advancements. Topological and structured photonics can probe, excite, and manipulate matter with unparalleled spatiotemporal accuracy to study new functional materials. They can also carry quantum-level information with many degrees of freedom without suffering decoherence, and thus render new technologies in quantum materials, information sciences, and (bio)chemical physics, among others. In the X-ray regime, ultrafast photon and electron sources, such as X-ray free-electron lasers (XFEL), have demonstrated the capacity to make molecular movies that reveal conformational dynamics in biomolecules and ultrafast chemistry at atomic-level spatial and femtosecond temporal resolutions. Motivated by their overarching relevance, we will review some of the most recent scientific and technological advances in photon and particle sources and some of their most important breakthroughs in life, chemistry, and energy sciences. We also discuss the potential impact of emerging technologies to tackle global challenges in environmental and chemical engineering, medical technologies, and other broader applications.

Biography: Sergio leads the Quantum Light-Matter Cooperative (Q-LMC), whose mission is to understand, design, and ultimately control light-driven physical processes to help solve interconnected socio-technological challenges. The Q-LMC is located across various areas in California: based at the UCLA Electrical & Computer Engineering Department and closely affiliated with the UCLA Physics & Astronomy Department, and Stanford University’s SLAC National Accelerator Laboratory, and the Linac Coherent Light Source. He graduated with a BS in Telecom Engineering from Tecnun, Universidad de Navarra in 2009. In 2012, he received his M.Sc. in Electrical and Computer Engineering from the National Science Foundation Engineering Research Center at Colorado State University. Later he continued his joint doctoral program simultaneously at the Research Laboratory of Electronics, Massachusetts Institute of Technology and the Center for Free Electron Laser Science, Deutsches Elektronen Synchrotron, and obtained his Ph.D. in Physics in 2015. He has received several awards recognizing his contributions to photon sciences and their application in ultrafast phenomena, including the 2021 Horizon Prize from the Royal Society of Chemistry, the 2021 SPIE Early Career Award, the Japan Society for the Promotion of Science Fellowship in 2019, SRI 2018 Young Scientist Award, and the PIER Helmholtz Foundation Dissertation Award in 2015, among others. He is also actively focused on professional service and outreach activities devoted to underrepresented minorities and to promote equity in educational and professional opportunities. Sergio also teaches ultrafast and quantum optics and accelerator physics courses periodically at the U.S. Particle Accelerator School. He currently holds two patents, is the author of over 80 peer-reviewed publications—including two book chapters—and has presented his work in over 50 international conferences.
