What paths do quantum particles, such as atoms or photons, follow through quantum state space? Scientists have used an "artificial atom" to continuously and repeatedly record the paths through quantum state space. From the cobweb of a million paths, a most likely path between two quantum states emerged, much as social trails emerge as people round off corners or cut across lawns between buildings.
Spintronics is a new field of electronics, using electron spin rather than motion. This technology requires insulating components that can control this quantum property. Scientists have shown experimentally that a novel material shows all the required properties.
It goes without saying that Superman can accomplish some pretty spectacular feats. But according to students, the Man of Steel actually achieves the impossible--by breaking the fundamental physics law of conservation of energy.
New research has offered a tantalizing new possibility in the realm of interstellar molecules and diffuse interstellar bands: these mysterious molecules may be silicon-capped hydrocarbons like SiC3H, SiC4H and SiC5H.
