"Unveiling the Power of Quantum Light in Strong-Field Non-Perturbative Physics"

Researchers at Technion–Israel Institute of Technology have developed a new theory describing non-perturbative interactions driven by quantum light. The theory, published in Nature Physics, provides insights into strong-field physics phenomena and could guide future experiments and the development of quantum technology. The researchers applied their framework to high harmonic generation (HHG) and demonstrated that the quantum state of light affects measurable quantities, such as the emitted spectrum. The theory has potential applications in attosecond pulse generation, quantum sensing, quantum imaging, and other strong-field physics phenomena.

Revolutionizing Electronics: Laser-Controlled Attosecond Electron Emission from Nanometric Metal Tips

Researchers have measured the quantum dynamics of electron emission from solids with attosecond precision using two-colour modulation spectroscopy of backscattering electrons. The experiment measured photoelectron spectra of electrons emitted from a sharp metallic tip as a function of the relative phase between the two colours. The emission duration was found to be 710 ± 30 attoseconds, opening the door to the precise active control of strong-field photoemission from solid state and other systems.
