Manipulating Twisted Electrons in Strong-Field Ionization
A. S. Maxwell, G. S. J. Armstrong, M. F. Ciappina +5
We investigate the discrete orbital angular momentum (OAM) of photoelectrons freed in strongfield ionization. We use these `twisted' electrons to provide an alternative interpretat…
A systematic construction of Gaussian basis sets for the description of laser field ionization and high-harmonic generation
Aleksander P. Woźniak, Michał Lesiuk, Michał Przybytek +8
A precise understanding of mechanisms governing the dynamics of electrons in atoms and molecules subjected to intense laser fields has a key importance for the description of attos…
Laser-assisted photoionization of argon atoms: streaking, sideband and pulse train studying cases
Renata Della Picca, Marcelo F. Ciappina, Maciej Lewenstein +1
We present a theoretical study of atomic laser-assisted photoionization emission (LAPE). We consider an atom driven by a linearly polarized XUV laser in two different scenarios: i)…
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…
Focal-shape effects on the efficiency of the tunnel-ionization probe for extreme laser intensities
M. F. Ciappina, E. E. Peganov, S. V. Popruzhenko
We examine the effect of laser focusing on the potential of a recently discussed scheme [M.F. Ciappina {\em et al}, Phys. Rev. A 99, 043405 (2019); Las. Phys. Lett. 17, 025301 (202…
Enhanced high-harmonic generation from chromium-doped magnesium oxide
V. E. Nefedova, S. Fröhlich, N. Tancogne-Dejean +15
High-order harmonic generation (HHG) from crystals offers a new source of coherent extreme ultraviolet (XUV) attosecond radiation.
