Attosecond metrology of bright quantum light
P. Stammer, J. Rivera-Dean, E. Pisanty +1
Attosecond metrology is the ability to measure ultrafast optical light-wave oscillations, yet its approach has been limited to classical fields. Hence, the influence of the fluctua…
Two-Electron Effects Extend High-Harmonic Generation into the keV Regime
Isobel McSweeney, Andres Marchisio, Javier Rivera-Dean +4
Two-electron processes can generate high harmonics beyond the conventional single-active-electron cutoff. Motivated by recent experimental evidence of an extended secondary plateau…
Emergence of Gaussian entanglement and non-Gaussianity in high-harmonic generation driven by bright squeezed light
J. Rivera-Dean, M. Even-Tzur, M. F. Ciappina +3
High harmonic generation (HHG) is a highly nonlinear optical process in which radiation from a strong driving field is up-converted into its high-order harmonics. In atomic systems…
Photon anti-bunching in high harmonic generation
Philipp Stammer, Javier Rivera-Dean, Maciej Lewenstein
Photon anti-bunching is the direct evidence for the existence of photons without having a classical counterpart. Unlike bunching of photons, which can have a semi-classical descrip…
Erasing photons from bright squeezed vacuum light via above-threshold ionization
J. Rivera-Dean, T. Rook, G. Singh +4
While the interface between strong-field physics and quantum optics offers a unique regime for combining extreme nonlinearity with quantum optical resources, its potential for gene…
Symmetry breaking by quantum light in solid-state high-harmonic generation
P. Stammer, J. Rivera-Dean, D. Kim +3
Symmetry governs nonlinear interactions in condensed matter systems, particularly in high-harmonic generation (HHG), the interplay between the driving field and crystal symmetries…
