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 ...

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

The team announced its “ultrahigh energy” neutrino on Wednesday, in a paper published in the journal Nature. The finding ...

"History shows us that whenever you do open a new 'energy window,' you never really know what you're going to find. It's completely unexplored." ...

Excitons, encountered in technologies like solar cells and TVs, are quasiparticles formed by an electron and a positively charged "hole," moving together in a semiconductor. Created when an electron ...

Excitons, quasiparticles formed by an electron and a hole, transfer energy without a net charge. Physicist Ivan Biaggio ...
