Fleeting electron-hole pairs are giving scientists a new window into optimizing light-emitting devices (LEDs). Using quantum ...

As we learn more about electricity, we have to talk about fields. As we learn more about electricity, we have to talk about fields. Electric fields may seem complicated, but they're really fascinating ...

To put one of physicists’ most important theories to the test, scientists go to extremes. Extremely strong electromagnetic fields, that is. The theory of quantum electrodynamics, which describes ...

Researchers in China have shown that applying strain to a composite material using an electric field induces a large and reversible caloric effect. This novel way of enhancing the caloric effect ...
