More DFT? Haven't we concluded that has little predictive power?
I’d be interested in seeing a source on that. My understanding was that it was a powerful and popular computational tool. The theory is approximate but approximate theories can still be quite useful if the approximation is a good one.
DFT is generally good for well characterized phenomenon. Superconductivity is a bit of an edge case, really dependent on quantum effects that you need ab-initio quantum mechanics simulations to predict.
My understanding is that the "99" in LK-99 is the year it they first synthesized the material, i.e. 1999. Assuming this is all true, why is it just now coming to light? Did they just not know what they had? (I have not been following this closely, maybe this has already been explained)
As I've read it, the first lead to the material was 99. 2018 They got funding to research it further, 2020 was a first attempt of publication at Nature that was retracted, further improvements were made until 22/23 were two patents were filled, then suddenly 10 days ago Kwon, one of the co-researchers jumped the gun publishing a paper with the details, on one hand fearing a leak of someone else publishing first as th…
Kwon is humanities' hero for leaking this knowledge to the world
The most interesting phenomenon revealed so far is that the room-temperature superconductor people and the generative-LLMs-are-God people draw on the same limited global pool of credulity, such that HN cannot be flooded with both ChatGPT worship and superconductor speculation at the same time.
It's so hard not to be crazy excited about the future. The past few months are proving to be an absolute breakout for the literal human race. So far we've seen: 1. in Dec 2022 We saw a fusion breakthrough seeing a net gain in energy 2. In March GPT-4 was released, which seems to be a seminal breakthrough in AI, and maybe of our first glimpse in what could become an AGI. 3. In May we find out apparently our government…

This is a silly thing to include on the list since it doesn't seem to be true?

More people saying it sounds feasibly like it could be a superconductor is great, but agreed - https://nitter.net/MichaelSFuhrer/status/1686267690770739200 and similar threads by actual experts in the field have outlined that DFT studies ignore a lot of variables that need to line up for superconductivity, in harsh contrast to techbros on Twitter claiming they're proof of the next thousand year golden era.
Thanks for linking someone who knows what he's talking about, very painful to see these DFT papers overhyped as some kind of proof... It proves almost nothing

Lol thank you. That’s hilarious. Also, I think it kind of sucks that all that UFO reverse engineering didn’t yield a high temperature superconductor before this… but I guess what can you expect when you sequester away all your materials, silo your research and in effect keep your neural network of nodes (as scientists) really small. This open shit, as flawed and maybe annoying as it is to some people, I think it’s a…
Perhaps, but the reverse engineering efforts you mention may have already led to incredible breakthroughs over the past few decades. Lasers, integrated circuits, Kevlar, fiber optics, and more technologies were said to have been seeded among the research community based on recovered UAP components. This is based on Army Colonel Philip Corso’s account in his memoir, “The Day After Roswell”. [1]

how about a 3rd group that is skeptical but not angry ? :) Am I bad that I'm waiting on oak ridge/los alamos/NASA/ONL/university of texas at austin to repro?
> These Cu d-d interactions right at the fermi energy give me huge hope. Feels very familiar to other superconductors (re: all the cuprates). As someone who is versed in semiconductor band structures but not superconductor band structures: What is it about Cu d-d interactions that causes the superconductivity? Degenerate energies in semiconductors don't give rise to electron pairing, so I'm a bit out to sea with the…
To be honest, this is a hunch thing more than a I can teach and explain it thing. To me it's just "a lot of the same stories" that are told about cuprates, and less of a "I can explain the mechanism". Roughly, one of the "properties" that shows up with these materials is that the 3d orbitals of coper atoms are involved in forming the bands near the fermi level. Couple that with the fun story of Cu electron configurat…

Fair enough, and thanks for the readout. I realized after posting I essentially demanded an explanation as to why the cuprates are high-Tc, which is probably its own Nobel prize.

I’ve seen several tweets implying the gubberment is rushing out RTAPS to “cover up” the alien stuff

Perhaps poorly worded, I meant since before . During Covid I lost a lot of zest for life, felt like I went to sleep in my 20s and woke up an old man.
I identify with that. It didn’t help that around the end of Covid I went through a terrible break up and all my grad school friends finished their degrees and moved while I was still working on mine. It felt like I went to the bathroom at a party and came back to an empty room and I had to stay and clean up. I knew I’d be done in a year or two, so it felt weird to try and find a new social group when I was on short t…
I can relate to both comments. Covid really sapped the life out of me. Some relationships broke down during isolation, I lost friends, my fiancée left, I felt stuck in a job that I hated... The research into LLMs and diffusion models started to wake me up, but this superconductor research has, for some reason, really awoken something in me. I feel excited about the future– my future!– for the first time in a while. My zest for life is back in full force, I feel like myself again, and I've been very excitedly telling everyone I know!
