The KATRIN experiment is closing in on the mass of the neutrino, which could point to new laws of particle physics and shape theories of cosmology.
One of the first quantum simulators has produced a puzzling phenomenon: a row of atoms that repeatedly pops back into place.
People have known about magnets since ancient times, but the physics of ferromagnetism remains a mystery. Now a familiar puzzle is getting physicists closer to the answer.
A new theory proposes that the quantum properties of an object extend into an “atmosphere” that surrounds the material.
