AWT and the quest for HT superconductivity

The interpretation of high temperature superconductivity by Aether theory is surprisingly easy - so it's apparent, just the common skepticism in particle models in physics has caused, such interpretation wasn't considered before years already. The forces between highly compressed electrons are compensating mutually, which leads into chaotic motion of charged particles, where energy can propagate in waves only, i.e. via bosons, formed by foamy particle condensate. Such system is indeed difficult to handle by explicit formal models indeed - but ab-initio computer simulations of quantum waves of many particles should reveal this behavior without problem - it's somewhat surprising, they weren't made already even in context of existing theories.

Anyway, to prepare condensed electron system isn't so trivial, as the "slippery" electrons cannot be simply compressed inside of vessel by piston, because they can pass through matter rather freely. For this purpose we can use a positively charged atoms, which attracts the electrons like money thrown into crowd attracts the people - the moment, when people starts to fight for free access is an analogy of quantum chaos, which we want form in electron cloud. The hole dopant atoms in semiconductor lattice can play a role of bait for electrons: the large group of holes attracts neighboring electrons, so they condensing around them. This model considers, electrons can move rather freely through lattice:

Unfortunately, the formation of isolated islands of condensed electrons isn't enough for establishing of superconductivity. Instead of this, so called the pseudogap state is formed, when the material exhibits most of bulk properties characteristic for true superconductors, but still hasn't a zero resistivity - this behavior is still a puzzle for mainstream physics, although its interpretation is easy in AWT. The increasing of hole density in general leads to the decreasing of the pressure inside of spherical islands and formation of metallic state, which is non-superconductive in general (the metals with spherical Fermi surface aren't good in superconductivity in general). Instead of this, a highly asymmetric lattices are preferred here, which are enabling the formation so called hole stripes. Under proper doping level, a less or more continuous superconducting phase can be formed successfully. The relatively sparse superlattice character of YBaCuO mixed oxide structure provides necessary distance separation of hole stripes. Repulsive forces of electrons inside of stripes must remain balanced by binding forces of remaining atoms.

It's apparent, the true room temperature superconductors must be formed a 3D superlattice of holes, injected into material in nanometer resolution - which isn't so easy to produce by contemporary technologies inside of regular crystals. Foam character of electron condensate manifests by formation of double walled anti-parallel spin domains along hole stripes in accordance to Colin Humphreys theory. We can consider them as a product of many Cooper pairs condensation along hole stripes, so that BCS/BEC theories still have their common point here.

The increasing level of doping manifests itself by transition from semi-ordered anti-ferromagnetic state in which magnetic layers are interspersed with non-magnetic layers. When the doping level is increased, magnetic ordering is suppressed on behalf of chaotic Fermi fluid near hole stripes and pseudogap in volume phase manifests itself. When the doping level increases even more, the pressure of neighboring atoms and degree of electron condensation may not be sufficient to maintain chaotic state anymore and the superconductor goes to metallic or even nonconducting state again. Bellow is the example of fractal principle, in which hole superlattices can be produced from ceramic precursors.

The surprising consequence of Aether model of HT superconductivity is, formation of superconductive phase isn't restricted just to solid phase. The electrons can condense even along surface of doped semiconductors, thus forming a superconductive channels around it. In such case, the formation of superconductive phase is even much more easier due the absence of atoms, prohibiting in electron free motion. It's virtually whole new approach to superconductivity at all.

Surprisingly enough, this mechanism was already revealed by prof. Johan F. Prins in 2002, who studied ion injection into diamonds (NS article, refusal). The n-doped diamonds are known for their very low work function due the strength of covalent C-C bonds. Therefore n-doped diamond binds a redundant electrons weakly and it can serve as a material for cold discharge cathodes, for example. At the moment, some oxygen ions are injected into diamond lattice by using of high voltage discharge, the hole atoms are attracting the surface electrons by such a way, they create a superconductive channels at the surface of diamond, which can be manifested both by zero resistivity in micrometer scale, both by Meissner-Ochsenfeld effect, because the surface of plasma treated diamonds repels the magnetic micro-particles reportedly.

Surprisingly these fundamental findings have met with rather low attention in scientific community so far, probably due somewhat dissenter approach of prof. Prins toward mainstream science, the quantum mechanics and BSC theory in particular (1, 2 -the fact, some theory cannot be applied to particular situation doesn't always mean, this theory is wrong). We can met with the same situation here, like at the case of Heim theory, antigravity or cold fusion research: the hysteresis of skepticism and peer-review based approach of mainstream science isn't very good in separation of progressive ideas from these crackpot ones. Of course, the delays in research resulting from pathological skepticism are of the very same cost, like the false belief in void speculations - they just cannot be calculated by explicit way.
