Geometric Control of Cat States in High Harmonic Generation
Arti Gaharwar, Rocío Borrego-Varillas, Marcelo F. Ciappina +6
High-harmonic generation (HHG) provides a powerful platform for exploring the interaction between intense laser fields and matter on ultrafast timescales. Beyond its conventional d…
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…
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…
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…
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…
Quantum state engineering of light using intensity measurements and post-selection
J. Rivera-Dean, Th. Lamprou, E. Pisanty +4
Quantum state engineering of light is of great interest for quantum technologies, particularly generating non-classical states of light, and is often studied through quantum condit…
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…
Nonclassical states of light after high-harmonic generation in semiconductors: a Bloch-based perspective
Javier Rivera-Dean, Philipp Stammer, Andrew S. Maxwell +6
High-harmonic generation has emerged as a pivotal process in strong-field physics, yielding extreme ultraviolet radiation and attosecond pulses with a wide range of applications. F…
Nonlinear optics using intense optical coherent state superpositions
Theocharis Lamprou, Javier Rivera-Dean, Philipp Stammer +2
Superpositions of coherent light states, are vital for quantum technologies. However, restrictions in existing state preparation and characterization schemes, in combination with d…
Light-matter entanglement after above-threshold ionization processes in atoms
Javier Rivera-Dean, Philipp Stammer, Andrew S. Maxwell +4
Light-matter entanglement plays a fundamental role in many applications of quantum information science. Thus, finding processes where it can be observed is an important task. Here,…
Generation of optical Schrödinger cat states in intense laser-matter interactions
Maciej Lewenstein, Marcelo F. Ciappina, Emilio Pisanty +4
The physics of intense laser-matter interactions is described by treating the light pulses classically, anticipating no need to access optical measurements beyond the classical lim…
Quantum optical signatures in strong-field laser physics: Infrared photon counting in high-order-harmonic generation
I. A. Gonoskov, N. Tsatrafyllis, I. K. Kominis +1
We analytically describe the strong-field light-electron interaction using a quantized coherent laser state with arbitrary photon number. We obtain a light-electron wave function w…
