April 14, 1932 was a day that transformed subatomic physics forever as a lithium atom was split using a proton beam.

A new proposal makes the case that paraparticles — a new category of quantum particle — could be created in exotic materials.

These invisible particles have been washing across the universe since the Big Bang 13.8 billion years ago. The number of ...

Imagine a cat in a box with a mechanism that has a 50/50 chance of killing it, depending on whether or not a quantum particle ...

In a breakthrough that brings nanoscience one step closer to precise control of chemical reactions, a team of researchers ...

Gold nanoclusters—tiny particles composed of from a few to hundreds of gold atoms—are ideal models for studying how atomic structure affects material properties. But tuning the structure of such ...
