Since the discovery of electron-wave duality, electron scattering instrumentation has
developed into a powerful array of techniques for revealing the atomic structure of matter …

Optically active molecular materials, such as organic conjugated polymers and biological
systems, are characterized by strong coupling between electronic and vibrational degrees of …

Following structural dynamics in real time is a fundamental goal towards a better
understanding of chemical reactions. Recording snapshots of individual molecules with …

Twenty years ago, the concept of aggregation‐induced emission (AIE) was proposed, and
this unique luminescent property has attracted scientific interest ever since. However, AIE …

The ultrafast photoinduced ring-opening of 1, 3-cyclohexadiene constitutes a textbook
example of electrocyclic reactions in organic chemistry and a model for photobiological …

Simultaneous observation of nuclear and electronic motion is crucial for a complete
understanding of molecular dynamics in excited electronic states. It is challenging for a …

Particles at relativistic energies form the basis of acceleration science. The emergence of
terahertz-driven acceleration promises vastly smaller and cost-efficient accelerators; …

We propose and demonstrate a novel scheme to produce ultrashort and ultrastable MeV
electron beam. In this scheme, the electron beam produced in a photocathode radio …

The electronic character of photoexcited molecules can abruptly change at avoided
crossings and conical intersections. Here, we report direct mapping of the coupled interplay …

The coherence and dephasing of vibrational motions of molecules constitute an integral part
of chemical dynamics, influence material properties and underpin schemes to control …
