There is a pre-theory of formative hypothesis which explains some of the mechanism of HTSC from physical observations.
Joe Eck, who is the Jed Rothwell of HTSC - has this theory listed on his site as “PWD theory”. http://www.superconductors.org/pwtheory.htm Notably - the superconductivity originates in the oxygen layers. Never mind that oxygen is not a conductor – what is needed at the early stage is not conductivity per se, but “paired electrons” or at least a heavy electron. These odd electrons must form in the interfacial region. This oddity may also imply that the active electrons are not valence electrons ! (meaning that they derive from “somewhere else”). Could the Cooper pair be two electrons in 3-space, held together by a positron in reciprocal space (1-space)? Which becomes the detail which could invoke Dirac and his “sea”. That is important to know, since oxides normally form dielectrics, except when they are in a resonant compressive mode. QUOTE: Ergo, there absolutely MUST be a difference in mass on opposite sides of the oxygen layer for superconductivity to occur. No periodic compression = no superconductivity. If there is a lesson here for LENR (which there could be since there are some similarities between the two in the appearance of heavy electrons, which could be paired in LENR or simply heavy), it would be that the active material needs to be nanostructured with planar oxygen layers, having two oscillators of different frequencies on either side of an oxide layer. There is a semi-precedent here - in the work of Arata, Ahern and others - with specialty material in which there is a micron-sized sphere of oxide material, such as zirconia, in which nanoparticles of active metal are embedded like the raisins in Panettone. It is possible that the oxygen from zirconia forms into layers in the spin-casting and that layer provides heavy electrons and perhaps positrons. Very interesting…. From: Kevin O'Malley And yet, there is still no established HTSC theory. Using the reasoning that has been applied to LENR... therefore, HTSC must not exist.
