Although technologies such as compact fluorescent lamps (CFLs) have emerged in the past few decades and will help achieve the goal of increased energy efficiency, solid-state lighting (SSL) stands to ...

At first, the photons settle into a state with zero momentum, but as this state 'fills up', pairs of photons begin to spill into the two adjacent states. This causes the polaritons to condense into ...

The Chinese Academy of Sciences has developed a light source that produces 193-nm DUV light, but it is years away from ...

For the first time, researchers transformed light into a quantum crystalline structure to create a "supersolid" that's both solid and liquid at the same time. Here’s what that means, and why it's such ...
