报告人简介

Marcelo Fabián Ciappina is a tenured Full Professor of Physics at the Guangdong Technion – Israel Institute of Technology (GTIIT). He received his PhD in Physics (with honours) from the Balseiro Institute (Argentina) in 2005 and later earned a DSc (Research Professor) from the Czech Academy of Sciences in 2019.

His research spans strong-field physics, ultrafast optics, and attosecond science, with recent work helping pioneer the emerging area of strong-field quantum optics. He has held research positions at leading international institutions, including the Max Planck Institute for Quantum Optics (Germany), ICFO – The Institute of Photonic Sciences (Spain), ELI-Beamlines (Czechia), and Auburn University (USA), among others.

Prof. Ciappina has authored more than 220 peer-reviewed publications, including papers in Nature Physics, Nature Communications, Reports on Progress in Physics, PNAS, Physical Review Letters, and Physical Review X, and edited the book High-Order Harmonic Generation in Solids (World Scientific, 2024). His work has received over 5,000 citations and an h-index of 39 (Web of Science). He serves as Associate Editor of Ultrafast Science and is a member of the Editorial Board of Journal of Physics B.

报告摘要

Do you ever wonder about the quantum-electrodynamics side of strong-field laser physics? Strong laser–matter interactions have been a central topic since high-power lasers emerged about half a century ago. They underpin foundational work in atomic, molecular, and optical physics and have helped shape areas such as attosecond science, nonlinear optics, and ultrafast optoelectronics. Although many results can be described using classical electromagnetic fields, recent fully quantized approaches suggest new directions worth exploring. This seminar surveys efforts to treat intense laser–atom interactions within a fully quantized framework. We discuss how such methods can enable the generation of controllable, high-photon-number entangled coherent states and coherent-state superpositions—capabilities that are difficult to capture within semiclassical theories. We then apply the formalism to processes including high-harmonic generation and above-threshold ionization, highlighting features that do not appear in purely classical descriptions. Finally, we consider how these ideas might extend to more complex materials and what they could mean for emerging quantum technologies, especially at the intersection of attosecond physics and quantum information science.
