As systems and devices become ever smaller, we're increasingly being forced to reconsider ideas we've relied on for decades. Unsurprisingly, this can be quite an undertaking — and none more so, ...

How it works: the wave in the foreground is an illustration of the phase of an out-of-equilibrium Bose-Einstein condensate in a 1D cavity, which belongs to the Kardar-Parisi-Zhang universality class.

Quantum dynamics—the study of how particles behave and interact in a quantum system—has long fascinated physicists due to its puzzling and sometimes bizarre behaviors. Unlike classical systems, where ...
