Over the past several decades, researchers have been making rapid progress in harnessing light to enable all sorts of ...

A world-famous light experiment from 1801 has now been carried out with sound for the first time. Research by physicists in ...

Researchers built a computer that performs AI calculations at light speed in a single shot. The breakthrough can help AI ...

Dark excitons are exotic light-matter states found in atomically thin semiconductors. They usually remain invisible because ...

A breakthrough in manipulating dark excitons could pave the way for next-generation quantum communication systems and ultra-compact photonic devices. A research group from the City University of New Y ...

A twist in the universe's first light could hint that scientists need to rethink physics. A pair of Japanese scientists looked at the polarization or orientation of light from the cosmic microwave ...

Given their tiny size, individual atoms are notoriously tricky to see and manipulate, but finding ways to do so would be extremely useful. The invention of the laser in the 1960s eventually led to the ...

Light's behavior seems counterintuitive. That is, until you figure out light is a wave. The way light behaves can seem very counterintuitive, and many physicists would agree with that, but once you ...
