Physicists have long relied on the idea that electrons behave like tiny particles zipping through materials, even though quantum physics says their exact position is fundamentally uncertain. Now, ...

Electrons are usually described as particles, but in a rare quantum material, that picture completely breaks down ...

Long before quantum mechanics existed, a scientist developed a powerful way of describing motion by drawing an analogy between particles and light.

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

An old puzzle in particle physics has been solved: How can quantum field theories be best formulated on a lattice to ...

Metal clusters made of thousands of atoms showed quantum interference, offering new insight into how large objects follow quantum rules.

Columnist Natalie Wolchover checks in with particle physicists more than a decade after the field entered a profound crisis.

As we journey from Newton's laws of gravity to Einstein's groundbreaking theory of relativity, and delve into the enigmatic ...

Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing ...
