The transfer of charge at the molecular level plays a fundamental role in many areas of
chemistry, physics, biology and materials science. Today, more than 60 years after the …

Optical modulation of high-harmonics generation in solids enables the detection of material
properties, such as the band structure, and promising new applications, such as super …

The ultrafast motion of electrons and holes after light-matter interaction is fundamental to a
broad range of chemical and biophysical processes. We advanced high-harmonic …

Molecular chirality plays an essential role in most biochemical processes. The observation
and quantification of chirality-sensitive signals, however, remains extremely challenging …

We present the experimental observation of two-center interference in the ionization time
delays of Kr 2. Using attosecond electron-ion-coincidence spectroscopy, we simultaneously …

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 …

Investigation on structures in the high-harmonic spectrum has provided profuse information
of molecular structure and dynamics in intense laser fields, based on which techniques of …

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 …

The description of the electronic structure of molecules in terms of molecular orbitals is a
highly successful concept in chemistry. However, it commonly fails if the electrons in a …

In recent years intense mid-infrared lasers with wavelength of a few microns have become
the standard tools for research in strong field physics laboratories worldwide. These lasers …
