Black Holes, Quantum Systems, Superconductors and Planck’s Constant are Related

Researchers from the CNRS and Université de Sherbrooke, have discovered a universal law for the electronic properties of high-temperature superconductors. They exposed superconductors to an intense magnetic field to weaken superconductivity and reveal underlying properties. They measured the variations of electrical resistivity up to -263 °C, and developed a predictive model that can be applied to multiple families of high-temperature superconductors.

This energy dissipation speed limit is linked to the numerical value of Planck’s constant, the fundamental quantity of quantum mechanics representing the smallest possible action that can be taken in nature.

Natalie Wolchover writing at the Atlantic describes how superconducting research could be near conceptual breakthroughs in understanding the physics of superconductors. There appears to be holographic duality that mathematically connects systems of scrambled quantum particles, like those in strange metals, to imaginary black holes in one higher dimension.

Black holes, quantum systems, superconductors and Planck’s constant appear to be related.

Nature Physics – Universal T-linear resistivity and Planckian dissipation in overdoped cuprates

Electrons inside a variety of ceramic crystals of cuprate superconductors seem to dissipate energy as quickly as possible, apparently bumping up against a fundamental quantum speed limit. Older studies found that other exotic superconducting compounds—strontium ruthenates, pnictides, tetramethyltetrathiafulvalenes also burn energy at what appears to be a maximum allowed rate.

Abstract – Universal T-linear resistivity and Planckian dissipation in overdoped cuprates

The perfectly linear temperature dependence of the electrical resistivity observed as T → 0 in a variety of metals close to a quantum critical point is a major puzzle of condensed-matter physics. Here we show that T-linear resistivity as T → 0 is a generic property of cuprates, associated with a universal scattering rate. We measured the low-temperature resistivity of the bilayer cuprate Bi2Sr2CaCu2O8+δ and found that it exhibits a T-linear dependence with the same slope as in the single-layer cuprates Bi2Sr2CuO6+δ, La1.6−xNd0.4SrxCuO4 and La2−xSrxCuO4, despite their very different Fermi surfaces and structural, superconducting and magnetic properties. We then show that the T-linear coefficient (per CuO2 plane), A1□, is given by the universal relation A1□TF = h/2e2, where e is the electron charge, h is the Planck constant and TF is the Fermi temperature. This relation, obtained by assuming that the scattering rate 1/τ of charge carriers reaches the Planckian limit whereby ħ/τ = kBT, works not only for hole-doped cuprates but also for electron-doped cuprates despite the different nature of their quantum critical point and strength of their electron correlations.

    If you want to know what is in reality going in the world and what may happen to you become familiar with the content of the file available at the website provided below.Please note this is not spam or advertisement, the file includes very important information, that every human should know about.Below I’m providing the link to the website with the file:

  2. There is , logically by definition of a Black Hole as a true singularity, just one Black hole that connects all universes. Once inside a BH, one is ‘everywhere’. The next question is how to ‘tune’ the BH …and the human brain, as a bio-quantum cyber machine (bio-Ai) will find the answer!

  3. That sort of makes sense.

    It has taken me 2 days to get my name working again. And I had to change the exact spelling and use a different email.

    About normal for a NBF comment system. But at least we get BOLD, italics, different fonts and

  4. Quantum energy with a new twist. Its like a radio signal but its not its like a energy to connect. Its a state of mind. I love it . Been reading about it. Never thought it would come out like this. So Awesome.

  5. … because …you don’t like physics? You think he does a bad job, but you don’t feel like providing any critical examples? You’re just a mean person?

  6. One of the principles of discovery is that, at more fundamental levels of the universe, the models become simpler, not more complex. This does not mean they will initially be easier to visualize. Our prior experiences and preconceptions can easily work against us in this regard. It is difficult, for example, for us to visualize a level of reality where aspects of physics integral to our daily experience, such as speed, or perhaps momentum, or even time, become meaningless, despite the fact that removing aspects, while adding few or none, will likely create a simpler model. It can be simpler even if our own prior experiences prevent it from initially being intuitive to us.
    It is also reasonable that most, if not all, aspects of physics operating at the most basic levels will already be familiar to us, even if we are unfamiliar with them operating in the absence of certain others.

  7. It’s how the comment system treats people who haven’t logged in prior to commenting. It makes up embarrassing names for them.

  8. Well, it describes this maximal dissipation state as a highly-entangled state (maximally entangled, presumably?) So the energy of electrons is immediately redistributed among all the other electrons in the strange metal at the fastest rate possible. They’re simply comparing this maximally entangled strange metal with the black hole and its maximal density. The strange metal’s effect on electron energy is constrained in the same way a black hole is on information.

  9. Fair enough. And, you are affiliated with spot?
    I ask because it seems to me that other posters from the past might have voiced an opinion by now, if they intend to come back.
    Simply frustrated here.

  10. Considering that they are all guests and their names match their pictures, I think it’s an automatically assigned name. I’ll try it.

  11. Has nbf been hacked?
    all just happened to choose similar names by chance?

  12. Better explained here:

    And the piece within the piece that talks specifically to your question here:


    • Electrons in “Strange Metals” exhibit a declining resistance with declining temperature that is a multiple of Plancks constant, suggesting there is a formula that explains the mechanism
    • This also suggests that “Strange metals” are dissipating the energy as fast as physics allows a bound to do so
    • ^This is referred to as “Planckian dissipation” (See first link for pretty diagrams and a more detailed explanation)
    • Black Holes supposedly do the equivalent of Planckian dissipation, reaching an upper bound for how fast they’re able to scramble the information falling in.
  13. The metals dissipation of energies show that, the electrons may have connected to a black hole otherwise how can you describe the law of conservation of energy??
