We report a theoretical investigation of photoionization by a pair of coherent, ultrashort,
fundamental and second-harmonic extreme-ultraviolet pulses, where the photon energies …

Molecular chirality has long been monitored in the frequency domain in the ultraviolet,
visible, and infrared regimes. Recently developed time-domain approaches can detect time …

In an intense X-ray free-electron laser (XFEL) pulse, atoms are sequentially ionised by
multiple X-ray photons. Photoionisation generally induces an alignment of the electron cloud …

Tailored light-matter interactions in the strong coupling regime enable the manipulation and
control of quantum systems with up to unit efficiency, with applications ranging from quantum …

We have generated elliptically polarized femtosecond pulses from a seeded free-electron
laser (FEL) in the spectral range 700–800 eV and conducted demonstrative experiments …

By means of analytical calculations based on first-order perturbation theory within the
electric dipole, laser, and rotating wave approximations, we investigate the linear (in …

We propose a directionality orthogonal double-slit interferometry to control photoelectron
dynamics in energy-and angle-resolved fashion. The two orthogonal components of …

The photoelectron momentum distribution (PMD) for the linear (in intensity) process of one-
photon single ionization of carbon monoxide is examined in the polarization plane for …

When a modulated electron beam passes through the crystal it emits superradiant
parametric X-ray emission (SPXE). Here we employ SPXE and demonstrate that it is …
