The heart of quantum mechanics is the wave-particle duality: matter and light possess both wave-like and particle-like attributes. Typically, the wave-like properties are inferred indirectly from the ...

Every once in a while we come across a physics story that seems very interesting – but we just don’t know what to make of it. The latest comes in the form of a press release from Brown University in ...

Electrons are elementary particles -- indivisible, unbreakable. But new research suggests the electron's quantum state -- the electron wave function -- can be separated into many parts. That has some ...
