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.
报告人简介： DSc Dr Marcelo Ciappina completed his PhD in Physics at Balseiro Institute, Argentina, in March 2005 and the Research Professor in Physico-Mathematical Sciences (DSc) dissertation (Habilitation) at the Czech Academy of Sciences, Czech Republic in June 2019. After several years of Postdoctoral and Senior positions all around the world, including, amongst others, various Max Planck Institutes in Germany (MPI-K Heidelberg, MPQ Garching and MPI-PKS Dresden), the Institute of Photonic Sciences (ICFO) in Spain, the Extreme Light Infrastructure (ELI)-Beamlines in Czech Republic, the Institute of High Performance Computing (IHPC) (A* STAR, Singapore) and the Auburn University (USA), he joined the GTIIT in fall 2020 as an Associate Professor and was promoted to Full Professor and granted tenure in January 2025. DSc Dr Marcelo Ciappina is a top-class expert in theory and numerical simulations of nonlinear laser interactions with atoms, molecules, and complex systems.
