Fractals promise higher-temperature superconductors - physics-math - 11 August 2010 - New Scientist

Fractals promise higher-temperature superconductors: "The researchers also found that the greater the length scales at which the pattern persisted - or the more complete its 'fractality' - the higher the maximum temperature at which the crystal could superconduct. Bianconi speculates that the scale-free distribution of the interstitial oxygen helps preserve the 'quantum coherence' of electrons in the crystal. Superconductivity is thought to depend on this property, which breaks down as temperature rises."
