We are pleased to invite you to a talk by Prof. Marcelo Ciappina of the Department of Physics of the Guangdong Technion - Israel Institute of Technology. Prof. Ciappina will talk about: “Quantum Electrodynamics of Strong Laser‑Matter Interaction: The Ongoing Journey and Beyond.”
And here es what you can expect: Do you ever wonder about the quantum electrodynamics aspects of strong laser - matter interactions? Strong field phenomena have fascinated scientists since the emergence of highpower lasers more than half a century ago, providing a foundation for research in atomic, molecular, and optical physics, as well as in attosecond science, nonlinear optics, and ultrafast optoelectronics. Although classical electromagnetic descriptions have long been sufficient, recent developments in fully quantized approaches are opening new perspectives. This talk will be about the ongoing efforts to describe intense laser - atom interactions from a quantized-field viewpoint.
Ciappinas team focuses on the generation of high-photon-number entangled coherent states and coherent-state superpositions - phenomena inaccessible to semiclassical theories. Applying this framework to processes such as high-harmonic generation and above threshold ionization reveals new mechanisms beyond classical understanding. Finally, the scientists around Ciappina explore the extension of these ideas to complex materials and their potential relevance to emerging quantum technologies, outlining a path that connects attosecond physics with quantum information science.
