(Phys.org)—A team of researchers with the University of Burgundy in France has shown that solitons can vibrate like real molecules when paired. They have published a paper describing their technique and findings in the ...
Matter is made up of atoms and electrons. Although seeing atoms is now possible, for example with modern electron microscopes, tracking atomic movements requires ultrashort measurement periods in the femtosecond and attosecond ...

Electrons move extremely rapidly inside atoms and molecules (the order of magnitude is the attosecond, i.e. 10-18 of a second). One way to observe these phenomena is to use isolated ultrashort pulses of light, which are successfully ...
