Understanding the relaxation pathways of photoexcited molecules is essential to gain
atomistic-level insight into photochemistry. We performed a time-resolved study of ultrafast …

Attosecond science requires a substantial rethinking of how to make measurements on very
short timescales; how to acquire the necessary equipment, technology, and personnel; and …

Understanding the evolution of molecular electronic structures is the key to explore and
control photochemical reactions and photobiological processes. Subjected to strong laser …

Understanding the quantum coherence effects is crucial for their promising applications,
such as engineering artificial photosynthesis, manipulating chemical reactions, and …

Ultrafast table-top X-ray spectroscopy at the carbon K-edge is used to measure the X-ray
spectral features of benzene radical cations (Bz+). The ground state of the cation is prepared …

Tracing ultrafast processes induced by interaction of light with matter is often very
challenging. In molecular systems, the initially created electronic coherence becomes …

The ultrafast structural, Jahn–Teller (JT) driven, electronic coherence mediated quantum
dynamics in the CH4+ and CD4+ cations that follows sudden ionization using an XUV …

High-harmonic generation is typically thought of as a sub-laser-cycle process, with the
electron's excursion in the continuum lasting a fraction of the optical cycle. However, it was …

Coherence can drive wave-like motion of electrons and nuclei in photoexcited systems,
which can yield fast and efficient ways to exert materials' functionalities beyond the …

We investigate the ultrafast vibronic dynamics triggered by intense femtosecond infrared
pulses in small molecules. Our study is based on numerical simulations performed with 2D …
