(Phys.org) —It's been a strong week for physics. One team showed that theoretically, superabsorption could be demonstrated using quantum engineering techniques—real world materials that take advantage of it could include ...
In 1921, Albert Einstein received the Nobel Prize in physics for the discovery that light is quantized, interacting with matter as a stream of particles called photons. Since these early days of quantum mechanics, physicists ...
