The random anti-laser

The laser is the perfect light source—as long as it is provided with energy, it generates light of a specific, well-defined colour. However, it is also possible to create its opposite—an object that perfectly absorbs ...

New shapes of laser beam 'sneak' through opaque media

Researchers have found a way to pre-treat a laser beam so that it enters opaque surfaces without dispersing—like a headlight that's able to cut through heavy fog at full strength.

Observation of quantized heating in quantum matter

Shaking a physical system typically heats it up, in the sense that the system continuously absorbs energy. When considering a circular shaking pattern, the amount of energy that is absorbed can potentially depend on the orientation ...
