A similarity in behavior has been discovered connecting high-temperature superconductors with black holes:
https://www.theatlantic.com/amp/article/576484/More specifically, it's the pre-superconductive transition phase known as "strange metal" which has been found to follow a Planckian limiting behavioral law for electron energy scattering, that resembles the informational scattering behavioral limit within a black hole.
Are we about to uncover some fundamental new Maxwellian analogy that sheds light on both superconductors and black holes?
Whereas the pre-superconductive transition state (aka "strange metal") maximally dissipates electron energy as fast as physically possible, the superconductive state is supposed to allow for perfect lossless flow of electrons and their energy.
Meanwhile, whereas a black hole maximally destroys/dissipates the structural information of matter as fast as physically possible, there's the idea that a wormhole could allow transit of matter without destroying its structural arrangement.
Is there an analogy here? Could the study of one system enable a better understanding of the other?
Does the strange metal operate as a sort of accelerated electrical earthing sink? Could that serve as an electricity dump?
The behavior of the Strange Metal phase is being called evidence of a state of maximum entanglement between electrons. The electrons in the strange metal are dissipating their energy at the maximum possible rate allowable, defined in relation to Planck's constant.
https://www.quantamagazine.org/universal-quantum-phenomenon-found-in-superconductors-20181119/ This was compared to the situation in black holes, whose matter is so dense that it's called a singularity, whereby all further matter coming in loses all its structural information. That information is then dissipated from the black hole at the maximum rate allowable, defined in relation to Planck's constant.
Entanglement has been called the basis for the continuity of spacetime (and maybe for Locality itself?)
https://www.ias.edu/ideas/2013/maldacena-entanglementThere are several interesting lessons regarding this picture of geometry emerging from entanglement. Perhaps the deepest one is that the peculiar and strange property of quantum mechanical entanglement is behind the beautiful continuity of spacetime. In other words, the solid and reliable structure of spacetime is due to the ghostly features of entanglement. As we entangle two systems with many degrees of freedom, it seems possible to generate a geometric connection between them, even though there is no direct interaction between the two systems.
So if the Strange Metal phase represents maximum entanglement among electrons, then I'm wondering if it could perhaps provide some analog to study Locality vs Non-Locality.
Anyhow, Condensed Matter Physicists seem to be excited about this latest discovery, because they feel it will lead to a fundamental improvement in understanding Superconductivity.
This doesn't belong in the "New Physics" section. It's not new physics. It's some new data for conventional physics.
Well, consider that this new behavioral law observed in superconductors is the new physics. Knowledge of superconductors is not comprehensive.
Furthermore, perhaps it could also serve as an analog to shed light on black holes.
Remember how, after Bose-Einstein condensates were first produced, subsequent experimentation was able to produce things like the Bosenova, which was like a miniature analog to the supernova phenomenon in massive stars:
https://en.wikipedia.org/wiki/BosenovaA bosenova or bose supernova is a very small, supernova-like explosion, which can be induced in a Bose–Einstein condensate (BEC) by changing the external magnetic field, so that the "self-scattering" interaction transitions from repulsive to attractive due to the Feshbach resonance, causing the BEC to "collapse and bounce" or "rebound."
Although the total energy of the explosion is very small, the "collapse and bounce" scenario qualitatively resembles a condensed matter version of a core-collapse supernova, hence the term bosenova.
...
The bosenova behaviour of a BEC may provide insights into the behavior of a neutron star, as well as into the possible properties of still-hypothetical boson stars and into the quantum theory of "collective phenomena" in general.
