A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.

In the quirky quantum world, particles can be affected by forces that they never directly encounter. A classic example is the ...
