A team of scientists at the California Institute of Technology (Caltech) has developed a tiny chip that can redirect light at ...

Polaritons are formed by the strong coupling of light and matter. When they mix together, all the matter is excited simultaneously—referred to as delocalization. This delocalization has the unique ...

Blue light has acquired a dubious reputation in recent years, frequently blamed for everything from disrupted sleep patterns to digital eye strain. This high-energy light, emitted abundantly by our ...

Scientists have pulled off a feat long considered out of reach: getting light to mimic the famous quantum Hall effect. In their experiment, photons drift sideways in perfectly defined, quantized steps ...
