Certain electromagnetic maths same as dark matter maths

Seeking Dark Matter on a Desktop

With its very small mass and lack of electric charge, the axion is a candidate for the mysterious dark matter particle. Yet, despite much effort, the axion has never been observed experimentally.

That may change thanks to the SIMES theorists' forefront research into topological insulators. In this small, newly discovered subset of materials, electrons travel with great difficulty through the interior but flow with much less resistance on the surface, much as they can in superconductive materials. Even better, they do this at room temperature.

"In their research into other applications for topological insulators, Zhang and his colleagues discovered that the electromagnetic behavior of topological insulators is described by the very same mathematical equations that describe the behavior of axions;wondrously, the laws of the universe related to axions are mirrored in this new class of materials. As a result of this mathematical parallel,the theorists posit that experiments on topological insulators can reveal much about the axions that are predicted to pervade the universe.

"That both are described by the same mathematical equation is the beauty of physics," said Zhang. "Mathematics is so powerful—it means we can study these things in topological insulators as if they were a baby universe."

In their paper, Zhang and his colleagues describe one particular class of topological insulator in which the parallel mathematics related to axions is most apparent, and suggest several experiments that could be performed to "see" axions in the electromagnetic behavior of topological insulators. These experiments could offer additional insight into the physical characteristics of the axion, insight that would simplify the astronomical search by giving observers a better idea of where to look for evidence of the axion hidden behind the overall roar of the universe.
"If we 'see' an axion in a tabletop experiment, it will be extremely illuminating," Zhang said. "It will help shed light on the dark matter mystery."

What would help shed light on the "dark matter mystery" is acknowledging what's staring them right in the face... electromagnetic fields in space.

Hi Solrey,
Interesting find.

No arguments from me but the psychology of the likes of Zhang preclude it. He's gone into raptures about the maths when the clue is stated quite clearly in the text: "the electromagnetic behavior of topological insulators". In other words the topolgical insulator isn't producing exotic particles (or whatever axions are).
To me, the logical thing to do would be to first look for electromagnetic behaviour in space and then look for axions in that environment. But then again, that might mess up the equations and we can't have that.

...research into topological insulators. In this small, newly discovered subset of materials, electrons travel with great difficulty through the interior but flow with much less resistance on the surface...

This sounds less like actual 'research' and more like mathematical manipulation to see what might happen mathematically. " Newly discovered subset of materials" does not mean that they have found , seen, touched, measured or created any new materials called topological insulators, in any real sense. How many subsets are there in the general category of materials? Why is it called a topological insulator rather than say, a surface conductor, or a quasi-static di-electric semiconductor? Resourceful misdirection? Even wires exhibit radial differences in conductivity at very high frequencies.

Anyone who can fog a mirror and has a normal education would read into this statement that someone has actually discovered some real material that functions as a topological insulator. But like invisible dark matter, it is not of this universe, but of the theoretician's universe of conceptual ideas couched in mathematical spins. WWMMS? (What would Miles Mathis say?)

Hi Jim. I guess I should have introduced some background on topological insulators. There have been some lab experiments and measurements which have preceded recent theoretical maths. I agree, pure maths is often GIGO but this seems to have real world foundations.

How to turn a topological insulator into a superconductor

Topological insulators are materials with a bulk electronic band gap and gapless, delocalized, surface states . One such compound, bismuth selenide (Bi2Se3), has received particular attention recently because it has a large band gap and a relatively simple surface band structure containing a single Dirac fermion mode with a lightlike, linear dispersion.

Superconductivity in these compounds was observed with standard resistivity and magnetization measurements that indicate a maximum transition temperature of around 4 K, as well as a strongly anisotropic upper critical magnetic field of about 5 T for fields along the weakly coupled direction, and about 2 T for fields parallel to the layered planes. Scanning tunneling microscopy experiments reveal that the copper atoms enter the interlayer regions in random positions, leading to a noticeable upward shift of the lattice parameter along the layer stacking direction.

This discovery of superconductivity in doped Bi2Se3 also causes one to pose questions related to the topological character of the parent compound, such as the following: Does the superconductor have gapless, delocalized surface states like the topological insulator does? If the new superconductor discovered by Hor et al. has gapless surface states itself, then the interface with its parent topological insulator may be even richer than previously thought. A further possibility raised by the work of Hor et al. is that one may be able to dope topological insulators with other transition metals besides copper. Introducing magnetic impurities, such as iron, just below the surface might open up a gap in the surface states, while preserving the band structure of the bulk. If that is the case, then the surface-doped compound would be magnetoelectric: applying a magnetic field would induce an electric dipole moment in the material and applying an electric field would create a magnetic dipole moment. If one dopes in magnetic impurities in the bulk, not just at the surface, one could make the material antiferromagnetic. The collective excitations would then couple to light in the same way that an axion (a leading dark matter candidate posited over thirty years ago to resolve the strong CP problem) does, giving the doped compound remarkable electro-optical properties in the far-infrared regime.

I see dusty plasma in space having similar properties related to the italicized text above. They think what's observed in space is due to dark matter "light coupling axions", but it's really just "impurities"/charge carriers/holes in the plasma crystal structure of cosmic dusty plasma that's analogous to the topological superconducting material.

Plasma Crystals form under certain conditions in a complex ('dusty') plasma. There, the electrically charged dust particles arrange in a regular macroscopic crystal lattice. This allows the investigation of the properties of condensed matter on the most fundamental level, the kinetic one.

Looks a lot like the new ESA Planck image, ironically enough that's the home of the plasma crystal experiments too.

Sometimes we think along a model to explain what we can and cannot see.

The links that I post take nothing away from the EU model, but try to explain the unexplained. We talk about electric fields and so on and yet we hold back from understanding the dynamos that create those elctric fields and filaments.

I think that in trying to understand condensed nuclear matter is a step in the right direction. There are many phses of nucelar matter and the mechanism for creating such phases is governed by Gravity and electromagnetic forces and yes electromagnetic reconnection of the fields.

Phases of hot nuclear matter at subnuclear densities

Abstract: Structure of hot dense matter at subnuclear densities is investigated by quantum molecular dynamics (QMD) simulations. We analyze nucleon distributions and nuclear shapes using two-point correlation functions and Minkowski functionals to determine the phase-separation line and to classify the phase of nuclear matter in terms of the nuclear structure. Obtained phase diagrams show that the density of the phase boundaries between the different nuclear structures decreases with increasing temperature due to the thermal expansion of nuclear matter region. The critical temperature for the phase separation is $\agt 6$ MeV for the proton fraction $x=0.5$ and $\agt 5$ MeV for $x=0.3$. Our result suggests the existence of "spongelike" phases with negative Euler characteristic in addition to the simple "pasta" phases in supernova cores until $T \alt 3$ MeV.

Hi Harry, you seem to have invented a few things here... (dynamo's & reconnection)... The electric model of the sun does not use these unobserved entities, one which directly violates maxwells.

Please see http://www.electric-cosmos.org/sun.htm for an explanation.

Today's orthodox thermonuclear models fail to explain many observed solar phenomena. The Electric Sun model is inherently predictive of all these observed phenomena. It is relatively simple. It is self consistent. And it does not require the existence of mysterious entities such as the unseen solar 'dynamo' genie that lurks somewhere beneath the surface of the fusion model. The Electric Sun model does not violate Maxwell's (reconnection of magnetic field lines!) equations as the fusion model does.

Solrey,

The funny thing about the plasma crystals is that they are being made in the same place as the PACS instrument on Herchel - the Max Planck institute near Munich in Germany. The same place, in fact, where Halton Arp works!!

And no, they don't talk to each other.

Mate they are no inventions. I think you may need to do a bit of research.

It has not come out of my back pocket.

It's plain to see that you have not read my posts corectly and you would find that I do not go along with mainstream thinking and the unseen solar dynamo genie that lurks somewhere beneath the surface of the fusion model.

I do not disagree with the Electric Universe logic which states that they do not know the properties of the centre of stars and comapct bodies. If I'm wrong here than please correct me by using science rather than opinion.

I do say that the compact bodies and there dynamics lies in the explanations put forward by supersymmetry and color-supperconductors, EM reconnection and so on, that may form a dynamo or a dynamotor, from these form dilatons, N/S poles that can create stable or unstable filaments that form the interconnection between star bodies.
