Predicting the Kondo Effect

Facebook X LinkedIn Email
SAN JOSE, Calif., Sept. 22, 2008 – Scientists at the IBM Almaden Research Center have discovered a major advancement in fundamental physics. For the first time ever, researchers are able to predict when the Kondo effect will occur. The Kondo effect is one of the few examples in physics where many particles collectively behave as one object, or a single quantum-mechanical body. Essentially, the Kondo effect occurs when electrons become trapped around the magnetic impurities in semiconductor materials, which prompts the electrons to change their spin. Sometimes, if the metal is cooled down to very low temperatures,...Read full article

    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
