During chemical reactions, atoms in the reacting substances break their bonds and re-arrange, forming different chemical ...

Ultrafast electron dynamics and charge migration describe the rapid movement and redistribution of electrons within molecules, processes that occur on attosecond to few-femtosecond timescales. Such ...

Nonadiabatic electron wavepacket dynamics is an emerging field that transcends the traditional Born–Oppenheimer approximation by explicitly considering the coupled evolution of electronic and nuclear ...

Fig. 1 The measured time-resolved KER spectrum (A) and the measured photoion momentum distributions at different delays (B) of O2 molecules. The coupled electronic and nuclear motions within a single ...

A team of researchers at the Max Born Institute have managed to fully characterize few-femtosecond-long light pulses tunable in the vacuum ultraviolet. These results unlock the possibility for ...

Electrons determine everything: how chemical reactions unfold, how materials conduct electricity, how biological molecules transfer energy, and how quantum technologies operate. But electron dynamics ...

A research team has achieved a major advance in X-ray science by generating unprecedented high-power attosecond hard X-ray pulses at megahertz repetition rates. This advancement opens new frontiers in ...

“Through this study, we were able to find clues about how electrons behave when they pass through the atomic wall,” stated Professor Dong Eon Kim. Physicists have been mystified for more than a ...
