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

When an intense laser pulse hits a stationary electron, it performs a trembling motion at the frequency of the light field.

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

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 ...

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 ...

The future of computing has arrived in a flash, literally. In A Nutshell Researchers created a computer that performs complex ...

Ether (or aether) is a term used in ancient mythology and medieval science to denote the matter that fills in the void of the universe. In the 19th century, physicists borrowed the concept to depict a ...

Superradiance When multiple electrons emit light in a coordinated manner, the resulting emission is much stronger than the sum of individual emissions. (Courtesy ...

Should physicists feel guilty about working on ideas with no real-world consequences, just because they’re intellectually beautiful? How should such work be evaluated? These questions arise often in ...
