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…

Recently, using conditioning approaches on the high-harmonic generation process induced by intense laser-atom interactions, we have developed a new method for the generation of opt…
High photon number entangled states and coherent state superposition from the extreme-ultraviolet to the far infrared
Philipp Stammer, Javier Rivera-Dean, Theocharis Lamprou +4
We present a theoretical demonstration on the generation of entangled coherent states and of coherent state superpositions, with photon numbers and frequencies orders of magnitude…
Dialogue on analytical and ab initio methods in attoscience
Gregory S. J. Armstrong, Margarita A. Khokhlova, Marie Labeye +3
The perceived dichotomy between analytical and ab initio approaches to theory in attosecond science is often seen as a source of tension and misconceptions. This Topical Review com…
The imaginary part of the high-harmonic cutoff
Emilio Pisanty, Marcelo F. Ciappina, Maciej Lewenstein
High-harmonic generation - the emission of high-frequency radiation by the ionization and subsequent recombination of an atomic electron driven by a strong laser field - is widely…

High-order harmonic generation stands as a unique nonlinear optical up-conversion process, mediated by a laser-driven electron recollision mechanism, which has been shown to conser…
Strong-field approximation in a rotating frame: High-order harmonic emission from p states in bicircular fields
Emilio Pisanty, Álvaro Jiménez-Galán
High-order harmonic generation with bicircular fields - the combination of counter-rotating circularly polarized pulses at different frequencies - results in a series of short-wave…
Slalom in complex time: emergence of low-energy structures in tunnel ionization via complex time contours
Emilio Pisanty, Misha Ivanov
The ionization of atoms by strong, low-frequency fields can generally be described well by assuming that the photoelectron is, after the ionization step, completely at the mercy of…
