(Phys.org)—It was another banner week for physics as one team at Cornell verified the 'Zeno effect,' whereby atoms won't move while observed. They conducted experiments in an Ultracold Lab and found that atoms that normally ...
To the list of potential applications of graphene – a two-dimensional semiconductor of pure carbon that is stronger and much faster than silicon – we can now add valleytronics, the coding of data in the wavelike motion ...
