以下のとおりセミナーを開催しました。
日時：２０２５年４月１１日（金）10:00～11:00
場所：東京大学理学部1号館4階439号室 および ZOOM（どちらも事前登録制）
講演者： Ido Kaminer (Prosessor, Electrical and Computer Engineering, Technion – Israel Institute of Technology)
講演題目： Strong-Field Quantum Optics
Decades of research in photonics established a mindset that quantum optics matters mostly for fewphoton processes, whereas high-intensity light behaves mostly classically. In this talk, I will review
recent developments that bridge this gap. In a series of recent works, we found quantum optical
effects intrinsic to strong-field processes, for example showing that high-harmonic generation and
other atto-science phenomena can become sensitive to the quantum nature of the driving field. I will
present key theoretical advances and pioneering experiments, showing how correlations between
emitters can get imprinted on emitted harmonics, and how high-harmonic spectra depend on the
photon statistics of the driving field. I will discuss ongoing experiments by us and by other groups
around the world, wrapping up with outlook on the prospects for engineering quantum many-photon
states and entangled attosecond pulses.
