The technique would be used to create metamaterials, meaning materials that don’t exist in nature. But nature itself still contains all kinds of stuff made from particles that can control their optic qualities. Cloaking might be possible.
The notion of a wave function refers to a way of describing quantum objects, including individual particles and more complex systems. A wave function assigns a value called probability amplitude to all points in space. The terms “wave” and “amplitude” imply that the objects described by wave functions behave much like waves.
Under the laws of classical physics, there are theoretical limits to these processes. But they are unrealistically high: For instance, we know that a car can never go faster than the speed of light. And no matter how much fuel is on the planet, or how much roadway or how strong the construction methods, no car will get close to going even 10 percent of the speed of light.
The researchers outfitted the microcavity with a semiconductor made from two chemical elements, one that is metallic and one that is not. This particular semiconductor was about the width of an atom, which is more than a million times smaller than a human hair.
ydrogen gas generated from various organic transformations indicated the successful performance of the new catalyst. “After completion of the reaction, the catalyst can be recovered to reuse for further reactions, simply by using a magnet,” Garima Jaiswal, a member of the research team, told India Science Wire.
