Quantum mechanics is one of the most successful theories in science — and makes much of modern life possible. Technologies ranging from computer chips to medical-imaging machines rely on the ...

A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

A new computational simulation of the early universe has revealed a fundamental, unbreakable geometric limit to the fabric of spacetime, dubbed the "Metric Wall." Discovered by independent physics ...

A 2,000-page monograph series proposes a new conceptual framework connecting quantum physics, gravitation and cosmological evolution.

More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that would quietly foreshadow one of the deepest truths in physics. While ...

The parity-identification problem fits naturally into this landscape. Parity is a global property, insensitive to most local details. In this respect, it resembles many other quantities studied in ...

Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

For many of us, advanced physics can be tough to understand to begin with, which makes it all the more impressive whenever someone earns a Nobel Prize for advancing the field even further. The latest ...

An international group of researchers have investigated the role of memory in quantum systems and dynamics. Their findings ...

At temperatures approaching absolute zero, most magnetic materials settle into tidy patterns. Their tiny magnetic moments, or ...
