The dynamics of electrons changes ever so slightly on each interaction with a photon. Physicists have now measured such interplay in its arguably purest form -- by recording the attosecond-scale time ...

A better understanding of how electrons convert energy into photons could lead to designing more efficient solar cells or better phototherapies for cancer. Researchers looking into the process have ...

Single-photon emission is a well-explored process. But in recent years interest in two-photon emission has grown. Nature Photonics spoke to Meir Orenstein and Alex Hayat in Israel about their latest ...

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

Up until the mid-20 th century, light was pretty ordinary. Yes, it was both a particle and a wave, but it didn’t do anything very weird. Then scientists, under-employed after the end of World War II, ...
