Electron Correlation Enables Phase-Coherent One-Attosecond Pulse Trains
Andrés Marchisio, Isobel McSweeney, Paraskevas Tzallas +2
Attosecond synthesis is ultimately a phase problem: a broad spectrum produces an ultrashort waveform only if its harmonics remain phase-locked. We show theoretically that correlate…
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…
Propagation of intense squeezed vacuum light in non-linear media
Javier Rivera-Dean, Deeksha Kanti, Philipp Stammer +5
Recent developments in quantum light engineering have enabled the use of infrared bright squeezed vacuum (BSV) femtosecond pulses in highly nonlinear optics, particularly strong fi…
Quantum Optics and Quantum Electrodynamics of Strong Field Processes
Marcelo F. Ciappina, Misha Yu. Ivanov, Maciej Lewenstein +3
In its beginnings, the physics of intense laser-matter interactions was the physics of multiphoton processes. The theory was reduced then to high-order perturbation theory, while t…
Recent developments in the generation of non-classical and entangled light states using intense laser-matter interactions
Th. Lamprou, P. Stammer, J. Rivera-Dean +4
Non-classical and entangled light states are of fundamental interest in quantum mechanics and they are a powerful tool for the emergence of new quantum technologies. The developmen…
Squeezed states of light after high-harmonic generation in excited atomic systems
J. Rivera-Dean, H. B. Crispin, P. Stammer +6
High-harmonic generation (HHG) has recently emerged as a promising method for generating non-classical states of light with frequencies spanning from the infrared up to the extreme…
