In physics, the conundrum known as the 'few-body problem,' how three or more interacting particles behave, has bedeviled scientists for centuries. Equations that describe the physics of few-body ...

University of Chicago physicists have succeeded in creating a vortex knot—a feat akin to tying a smoke ring into a knot. Linked and knotted vortex loops have existed in theory for more than a century, ...

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 ...
