The timescales underlying fundamental chemical processes are determined by nuclear and electron dynamics involving atto-, femto- and picosecond events. Probing these events through time-resolved ...

Attosecond pulses capture ultrafast electron and light–matter dynamics on the shortest timescales accessible to controlled experiments, making them indispensable tools for ultrafast spectroscopy, ...

New measurements in germanium reveal how excited electrons drive lattice vibrations that govern energy flow and heating in semiconductors. (Nanowerk News) Whether in a smartphone or laptop, ...

Since the first demonstration of the laser in the 1960s, laser spectroscopy has become an essential tool for studying the detailed structures and dynamics of atoms and molecules. Advances in laser ...

A project at China's Zhejiang Normal University (ZJNU) has applied laser spectroscopy to bomb-peak dating, potentially assisting a number of carbon-dating and forensic applications. Bomb-peak dating ...
