Photoelectron holography constitutes a powerful tool for the ultrafast imaging of matter, as it
combines high electron currents with subfemtosecond resolution, and gives information …

The availability of attosecond-duration extreme ultraviolet or soft X-ray light sources has
opened up new fields of research in atomic and molecular physics. These pulses can be as …

High-order harmonics extending to the X-ray region generated in a gas medium by intense
lasers offer the potential for providing tabletop broadband light sources but so far are limited …

Nonadiabatic dynamics around an avoided crossing or a conical intersection play a crucial
role in the photoinduced processes of most polyatomic molecules. The present work shows …

Cooper minimum structure of high-order harmonic spectra from atoms or molecules has
been extensively studied. In this paper, we demonstrate that the crystal harmonic spectra …

High harmonic generation (HHG) takes place in all phases of matter. In gaseous atomic and
molecular media, it has been extensively studied and is very well understood. In solids …

We report the observation of macroscopic field-free orientation, ie, more than 73% of CO
molecules pointing in the same direction. This is achieved through an all-optical scheme …

The high-order harmonic generation process of H 2+ in a co-rotating two-color circularly
polarized laser pulse was investigated by numerically solving the time-dependent …

Here we present a fully ab initio study of the high-order harmonic generation (HHG)
spectrum of aligned CO2 molecules. The calculations have been performed by using the …

All attosecond time-resolved measurements have so far relied on the use of intense near-
infrared laser pulses. In particular, attosecond streaking, laser-induced electron diffraction …
