Can a single particle have a temperature? It may seem impossible with our standard understanding of temperature, but columnist Jacklin Kwan finds that it’s not exactly ruled out in the quantum realm ...

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

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

Abstract: High-fidelity quantum control is one of the key elements in quantum computing and information processing. In view of possible inaccuracies in quantum system modeling and inevitable errors in ...

The way time ticks forward in our universe has long stumped physicists. Now, a new set of tools from entangled atoms to black ...

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

Physicists have discovered that hidden magnetic order plays a key role in the pseudogap, a puzzling state of matter that ...

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

When quantum spins interact, they can produce collective behaviors that defy long-standing expectations. Researchers have now shown that the Kondo effect behaves very differently depending on spin ...

Scientists have shown that it may be possible to transform materials simply by triggering internal quantum ripples rather than blasting them with intense light. Imagine being able to change what a ...

What if you could create new materials just by shining a light at them? To most, this sounds like science fiction or alchemy, but to physicists investigating the burgeoning field of Floquet ...
