    This is a really great article on the recent discovery of a fundamentally new property of well known superconductors. I'm going to have research this, because I may be able to explain how superconductors work and the thermodynamics being similar to a black hole could be important for my work. This is likely it, an explanation for superconductivity, and I'm almost certain its not any explanation they expect. Surprises entail surprising consequences and, the more surprising, the more fundamental the insights, including the possible existence of "unparticles" of unknown properties.

    The article doesn't mention it, but recently researchers managed to achieve sub-absolute zero temperatures, that were actually infinite hot. Assuming that what does not exist defines what does, then extremes like existence and nonexistence, infinitely hot or cold, would express the limits of how far we can probe nature. The unparticles sound an awful lot like syntropy or a singularity, and I have often wondered if tests on superconductors might be the first experimental evidence for a theory of everything, simply because they've done a lot more of these kinds of cold temperature experiments in labs, because they are relatively cheap and take up limited space. Academics are always pressed for space.

    They've had all this since Roswell hey.

    They might have, but now it finally coming out. The singularity is collapsing and that means their past is catching up to them with a vengeance.

    I've been calling out the existence of alien technology for like the 8 years I have been here. :p

    Unknown Unknowables Behind the Curtains

    Invisible pixies both thrill and delight,
    Tripping the light fantastic with mass!
    Wherever go, they are already there!
    Faster than a speeding bullet!
    More powerful than a locomotive!
    Dancing between invisible moonbeams,
    Between everything and nothing,
    In between gigs, hanging out backsage,
    Waiting on the next Heat Death,
    On their way to the next Big Crunch!
    Chi is not for Cheetos.

    ‘Unparticles’ May Hold The Key To Superconductivity, Say Physicists
    A mysterious form of matter may help to explain one of the most important phenomena in physics

    ‘Unparticles’ May Hold The Key To Superconductivity, Say Physicists

    excerpt:

    "Back in 2007, the Harvard physicist Howard Georgi put forward an exotic and revolutionary new theory of physics. Until then, all of physics could be described in terms of particles and the forces between them.

    Georgi proposed something different — that there was an entire sector of physics involving energy, momentum and mass but with no particles. He coined this stuff “unparticles” and developed the mathematical framework that describes it and its properties.

    Nobody has ever observed an unparticle but physicists have toyed with this new model of physics and proposed various ways in which it might be measured for the first time. Indeed, the most recent thinking is that conventional particles can behave like unparticles under certain conditions.

    Today, James LeBlanc and Adolfo Grushin at the Max Planck Institute for the Physics of Complex Systems in Dresden, Germany, say this effect may explain unconventional superconductivity, the ability for materials to conduct with zero resistance.

    Conventional superconductivity was explained in the 1950s and thought to work only at very low temperature. But the discovery of superconductivity at relatively high temperatures in the 1980s took physicists entirely by surprise and they have struggled to understand this unconventional phenomenon ever since. Now LeBlanc and Grushin are suggesting that unparticles could be the key."

    An article that gives a mathematical treatment of unparticle mediated superconductivity


    Unparticle mediated superconductivity

    [1407.8492] Unparticle mediated superconductivity

    free pdf:

    https://arxiv.org/pdf/1407.8492

    excerpt:

    "In this work we have described how it is possible for unparticles in strongly correlated matter to mediate superconductivity. We have shown that this scenario can depart strongly from the conventional BCS paradigm. In particular, we have found that for swave superconductivity, the superconducting gap acquires an unusual dependence on the DOS at the Fermi level that can even vanish when the scaling dimension of the mediating unparticle is dU = 3/2. Interestingly, this vanishing dependence on the density of states occurs at the value of dU where kinetic and potential energy terms scale equally in energy [54]. This may be important in the high-Tc materials which are thought to switch from typical potential energy driven pairing in the overdoped side of the phase diagram, to kinetic energy driven in the underdoped [55, 56]. Such a crossover may correspond to a similar crossover of the unparticle scaling determined by the value of dU."

    Unparticles is merely a foot in the door, as far as I'm concerned and, although its an important foot in the door, it is apparently just one of many emerging feet in the door prepared to explore beyond the Standard Theory. Trying to put all of them in context is turning my brain into Jell-O, but its exciting!
