Scientists Create "Strange Metal" Packed With Entangled Electrons:
An international team of researchers has created what's called a strange metal — and they say it could help harness the potential of the quantum world in a practical way.
Specifically, the metal provides evidence for the quantum entanglement nature of quantum criticality.
[...] The researchers used the elements ytterbium, rhodium, and silicon to create a type of metal in which the electrons act as a unit rather than independently like they would in a regular metal, such as copper or gold.
When at the lowest temperature theoretically possible — absolute zero, or -273.15 degrees Celsius (-459.67 degrees Fahrenheit) — the team's strange metal undergoes a transition from a quantum phase, in which it forms a magnetic order, to another phase in which is doesn't.
While conducting experiments on ultrapure films made from the metal, the team noticed quantum entanglement among billions of billions of electrons in it.
But it's still no workaround for the light speed limit, not even if you use octinons.

The biggest revelation is that they claim to have reached absolute zero!

If you read carefully it could say they created this metal then calculated the behavior at absolute zero.

Sod zero-temperature, I wanna know how this metal behaves when zero-sized?

They look at the scaling of charge fluctuations as they approach 0K, they don't claim to reach 0K. In the paper it says they went down to 1.4K, pretty low, but not a record. Just low enough to see the trend.
In the theory paper for the simulation, they also go to a very low temperature, I think it said 1/40 of the bandwidth.

the problem is a ton of materials don't follow predicted pattern but become superconductors, so their oredictions are worthless?
