Electron correlation and short-range dynamics in attosecond angular streaking
G. S. J. Armstrong, D. D. A. Clarke, J. Benda +2
We employ the R-matrix with time-dependence method to study attosecond angular streaking of F. Using this negative ion, free of long-range Coulomb interactions, we elucidate th…
Pulse-shape control of two-color interference in high-order-harmonic generation
K. R. Hamilton, H. W. van der Hart, A. C. Brown
We report on calculations of harmonic generation by neon in a mixed (800-nm + time-delayed 400-nm) laser pulse scheme. In contrast with previous studies we employ a short (few-cycl…
XUV-initiated high harmonic generation: driving inner valence electrons using below-threshold-energy XUV light
A. C. Brown, H. W. van der Hart
We propose a novel scheme for resolving the contribution of inner- and outer-valence electrons in XUV-initiated high-harmonic generation in neon. By probing the atom with a low ene…
Time-resolved four-wave-mixing spectroscopy for inner-valence transitions
Thomas Ding, Christian Ott, Andreas Kaldun +9
Non-collinear four-wave mixing (FWM) techniques at near-infrared (NIR), visible, and ultraviolet frequencies have been widely used to map vibrational and electronic couplings, typi…
Multiphoton inner-shell ionization of the carbon atom
H. F. Rey, H. W. van der Hart
We apply time-dependent R-matrix theory to study inner-shell ionization of C atoms in ultra-short high-frequency light fields with a photon energy between 170 and 245 eV. At an int…
A practical scheme for generating isolated elliptically polarized attosecond pulses using bi-chromatic counter rotating circularly polarized laser fields
Lukas Medišauskas, Jack Wragg, Hugo van der Haart +1
Spectra of circularly polarized harmonics is calculated by numerically solving the Time-Dependent Schrödinger Equation for a 2D model of Ne atom using circularly polarized fundamen…
