Scientists have found a way to achieve negative refraction—where light bends the "wrong" way—using carefully arranged atomic arrays instead of engineered metamaterials. This breakthrough has enormous ...

Researchers have developed a novel experimental platform to measure the electric fields of light trapped between two mirrors with a sub-cycle precision.

For the first time, researchers have been able to measure the quantum state of electrons ejected from atoms that have ...

An unexpected television signal traced to an airplane led to a new method for pinpointing unwanted radio signals, as growing ...
