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 ...

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.

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 ...

By bringing the long-standing and opposing views of quantum mechanics together to form a single cohesive theory, a research ...

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 ...

Physicists have transformed a decades-old technique for simplifying quantum equations into a reusable, user-friendly "conversion table" that works on a laptop and returns results within hours. When ...

I have long been fascinated by the strong attraction many people feel toward quantum field theory as a way to explain extraordinary experiences. As a psychiatrist interested in coincidences and the ...
