Abstracts

We show that high temperature superconductivity contrary to the Bardeen-Cooper-Schrieffer /BCS/ superconductors exhibits three important energy scales. The highest is associated with the formation of Cooper pairs coupled due to the magnetic fracton excitations, the second (pseudogap) we ascribe to the formation of coherent but not nonsuperfluid condensate. The lowest energy scale (superconducting gap) we associate with the onset of superfluidity of the condensate that is due to the phonon aided fracton hopping.
