Enhanced Strange Metallicity due to Hubbard-$U$ Coulomb Repulsion
A model of electrons that has a particular Coulomb repulsion and is coupled to a 2D bosonic bath shows a quantum critical point where traditional Fermi-liquid physics breaks down, resulting in a so-ca...

As a young researcher, I find this legacy of dubious claims disheartening. Nobody wants to dedicate the beginning of their career to work that might be based on bogus results. This steers a lot of people away from what could otherwise be a very productive field.

Some strong criticism of Šmejkal et al.'s work on altermagnetism and its potential for spintronics.
Trump: "Like on tractors that can handle anything from hurricanes to lightning to anything. They use magnets. It's a new theory -- magnets. They're gonna lift the planes up. And it doesn't work."

@quantamagazine.bsky.social always manages to find problems I had never considered. Very curious to see some consequences, especially Schmalian's hope for infinite T SC!
Normally, heat disrupts the quantum ordering that makes superconductivity possible. But a new way of heatproofing quantum patterns may one day help physicists blow past this limitation.

Heat is supposed to ruin anything it touches. But physicists have shown that an idealized form of magnetism is heatproof.

you know what's a good idea as the climate changes, is firing the people working on crop yields
Another example of what cutting science funding is doing to our leading university research programs in the U.S.: dismantling things like the Soybean Innovation Lab at UIUC, which have made US crop yields dramatically higher.

“Constitutional crisis” does not even begin to capture the radicalism of what is unfolding in the federal bureaucracy and of what Congress’s decision not to act may liquidate in terms of constitutional meaning.”
