Scientists looked at how an electrical charge would move through a barrier of silicon, germanium and tin, part a quantum well. They thought the electrical charge would move more slowly, but mobility ...

Olival Freire Jr is a professor of physics and the history of physics at the Federal University of Bahia, Brazil. What makes matter stable? Why are atoms as they are? Why do different materials vary ...

Physicists directly observed ultracold atoms in an 'edge state,' flowing along a boundary without resistance. The research could help physicists manipulate electrons to flow without friction in ...

Scientists have demonstrated that atoms can exhibit wave-like behavior, challenging long-held assumptions that experiments of this nature were impossible and opening new doors in quantum physics. The ...

In a new study, physicists at the University of Colorado Boulder have used a cloud of atoms chilled down to incredibly cold temperatures to simultaneously measure acceleration in three dimensions—a ...

A cloud of atoms with a temperature beyond absolute zero – which is also bizarrely hotter than any positive temperature imaginable – could be a mysterious new quantum state of matter. Luca Donini at ...
