Information processing technologies that are typically based on electron charges can also theoretically make use of the electric spin. Magnon spintronics can harness quantized spin waves, magnons, as carriers of spin currents ...
Rice University atomic physicists have verified a key prediction from a 55-year-old theory about one-dimensional electronics that is increasingly relevant thanks to Silicon Valley's inexorable quest for miniaturization.
