An experiment 180 years ago first demonstrated a connection between light and electromagnetism – but the link is deeper than ...

For nearly two centuries, physics textbooks have treated light as magnetically indifferent to the materials it passes through ...

If so, laws might change when the universe itself changes phase. In the early universe, as temperatures and densities shifted, forces split apart from a unified origin. What we call “laws” may be like ...

The engineering of optically synthesized magnetic fields allows neutral atoms to emulate charged behavior, paving the way for ...

In 1887, one of the most important experiments in the history of physics took place. American scientists Michelson and Morley ...

A cloud of ultracold atoms is like a motel with a neon “no vacancy” sign. If a guest at the motel wants to switch rooms, they’re out of luck. No vacant rooms means there’s no choice but to stay put.

Researchers from the Department of Molecular Physics at the Fritz Haber Institute have demonstrated the first magneto-optical ...
