In order to understand the behaviour of atoms and molecules, it does not suffice to know their structure, but physicists furthermore want to observe their motions, and the motions of the electrons that are contained in them....

Combining optical measurements with theoretical modeling, researchers at AMOLF, IBM and Harvard University have succeeded in characterizing the molecular memory that controls the locomotion of bacteria – the simplest forms of...

For the first time ever, a European research team has managed to use attosecond laser pulses to observe the motion of electrons in molecules. This work is an important step in unraveling the movements of electrons that are at the...
