We make a detailed assessment of which form of the dipole operator to use in calculating high order harmonic generation within the framework of the strong field approximation, and look specifically at the role the form plays in the inclusion of multi

We investigate high-order harmonic spectra from aligned diatomic molecules in intense driving fields whose components have orthogonal polarizations. We focus on how the driving-field ellipticity influences structural interference patterns in a macros

We investigate HHG with Bohmian trajectories, including single-trajectory, ensemble analysis, time-frequency maps and wave-packet reconstruction. The innermost trajectory can be associated to an ensemble of unbound classical trajectories, and best re

We present a generalised two-centre interference condition for molecular HHG in orthogonally polarised driving fields. The ellipticity adds a dynamic shift associated with the angle of return of the electronic wavepacket to the alignment angle.

We investigate the influence of intense driving fields whose components exhibit orthogonal polarizations on high-order-harmonic spectra from aligned diatomic molecules. We derive a generalized two-center interference condition, which accounts for $s\

We perform a Bohmian-trajectory analysis of high-order harmonic generation (HHG), focusing on the fact that typical HHG spectra are best reproduced by the Bohmian trajectory starting at the innermost part of the core [Phys. Rev. A \textbf{88}, 023415

We investigate high-order harmonic generation from a Bohmian-mechanical perspective, and find that the innermost part of the core, represented by a single Bohmian trajectory, leads to the main contributions to the high-harmonic spectra. Using time-fr

We address the influence of the molecular orbital geometry and of the molecular alignment with respect to the laser-field polarization on laser-induced nonsequential double ionization of diatomic molecules for different molecular species, namely $\ma
