You guys do know the affordability of the chips you’re using to comment on this is a direct consequence of TSMC “efficiency”, right?

Mind you, the DFT calculation from the Griffin paper is not a proof of LK 99 being a superconductor in any way. What it showed is the (potential) formation of flat bands near the Fermi surface. Band dispersion is associated with the kinetic energy of the electrons, so materials with flat band (and therefore electrons with suppressed kinetic energy) at the Fermi surface are more susceptible to interaction effect (and strong interaction causes all sorts of nonintuitive quantum effects). I’m not a DFT expert in any sense, but from what I’ve heard, it is quite easy to “tune” your model to produce narrow (the limit of which being flat) bands from substitutions (e.g. the Cu substitution in this case) and such, which don’t necessarily lead to superconductivity.

So I’ll take the DFT papers (there are quite a few now) as saying, “hey you want some flat band? Here’s some. We’ve done our part. Now some other theorist, do your magic and conjure up some superconductivity”. It’s a cog in the full picture, if there is a full picture

The point is there are established conventions among the practitioners on how these are pronounced, and not getting them right says something about the youtuber who may otherwise appear as an expert.

You might be right on how the name ‘Schrieffer’ should be pronounced in its original tongue, but I’ve heard multiple former students and colleagues of Bob Schrieffer pronounce it otherwise to conclude that theirs is probably how Schrieffer himself intended his name to be pronounced.

Yeah, can’t wait to hear economists’ take, or The Economist’s…

Give me a way to physically shut off the microphone (like a camera shield on business laptops), then we will talk.

Strange topics had popped up in my Google feed after l spoke to someone about something I’ve never googled before

Hi Joe Brian

Not to be snobbish or anything, but at this juncture I wouldn’t trust anyone who can’t pronounce arXiv (or Schrieffer for that matter) correctly to explain room temperature superconductivity to me. Hell I barely believe anyone with a materials/physics degree…

In fact this goes all the way back to Hamilton when he invented quaternion, in which i,j,k are used as basis vectors (which are generalizations of the imaginary i). Later Gibbs dropped the scalar component and gave us the modern vector.
