When atoms collide, their exact structure—for example, the number of electrons they have or even the quantum spin of their ...

It may be the smallest, shortest chorus dance ever recorded. An international team of researchers observed how electrons, excited by ultrafast light pulses, danced in unison around a particle less ...

Physicists have found a simple and effective way to skip over an energy level in a three-state system, potentially leading to ...

Astrophysicists have observed our central supermassive black hole. They found the accretion disk is constantly emitting flares without periods of rest. Shorter, faint flares and longer, bright flares ...
