“Trapping electrons in a crystal” is such a nonsensical way of conveying the idea of a flat band. Most isolated crystals trap all the electrons they have inside of them, or else the world will be full of free roaming electrons!

This is not surprising at all. A well-matching referee is a scarce resource. Higher impact journals can typically find better-matching referees due to their perceived prestige, as well as the much lower number of manuscripts passing through editors and making to the referees (it is well known that high impact factor is a consequence of editorial selectivity). A better matching referee is more likely to comment on the more pertinent points on the actual research and will therefore not linger too much on superficial aspects such as grammar etc (which, once/if a manuscript is accepted, will be handled by copy editors). The same referee will likely also use different criteria for different journals regarding acceptance, where they usually focus more on high level stuff such as perceived innovation or impact to field etc for high profile journals, and more on technical details for more run-of-the-mill types.

Thanks for the pointer, I actually have accessibility turned on via bitwarden (a password manager) and never thought that might be correlated. Will test when I get the chance.

I’ve seen similar things with a physical keyboard connected. There are plenty other Android apps that can handle connected keyboards corrected by not showing the on screen keyboard(OSK) (the now defunct RIF being one). Right now the only way to not have flashing OSK is to turn it off system wide under android settings, which is not ideal (because it won’t turn itself on automatically when the physical keyboard disconnects)

Well the band wagon has turned 180, now it’s fashionable to point out the flaws. My issue with this kind of videos is really, where are you in the early days of the hype, when the public needed cautions the most? A convenient naysayer when all the actual hard works have been done elsewhere

You need to forget about the details in order to grasp the essence.

Referee reports are reports produced – for free – by the peer review referees of their opinions / suggestions / comments on the papers that academic journals ask them to review on their behalf. Editors of the journals usually make their decision on whether a paper can be published as is, needs revision (and then to which degree), or rejected, according to the referee reports. In case of a revision, the authors of a paper will need to address the concerns in the referee reports in detail, often providing additional supporting materials etc. Referees are typically practicing scientists themselves and perform peer review for the good of the community (at least in theory). Most of the referees are anonymous to protect them from backlashes from criticizing the papers they review, particularly when some coauthor is a big shot. To be fair, not all referee reports are constructive, but at least the majority of them perform adequate gate-keeping to sift out the obvious bad apples.

giving me a quick overview of what that is and how it applies?

Not sure I understand your question. What are you referring to by “that” and “it”?

Most early career people will not be willing to have their names publicized alongside their referee reports, because that will be too much risk for their career advancement. And let’s face it, most referees are early career just by the sheer amount of papers out there to review.

OK, but where are they when the LK99 first came onto scene?

Documentation is different from demonstration. Text (with graph or animation interspersed to unpack unintuitive terms) wins for documentation. Video could be good for demo if presented in a no-nonsense manner.

Scale of velocity as well so we have a more complete picture in phase space

The referees who let this slip are either brilliant or lazy (or both, I guess)

Well, even the picture is in the picture…

Now let’s see which youtube “science channels” do a debunk on their own content pushed out a mere month ago.

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

Copy text doesn’t cut it because sometimes I just need to select a sentence or a link, not the full text.

This is also a problem for the post itself, not just comments.

On android, long press for text selection is standard operation.

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

Resubmitting to multiple journals is not a typical (nor the “right” one however it is interpreted) strategy though (at least not in physical sciences). You’ll usually ping the handling editor, who will then contact the referee on your behalf. The referee will then either “promise a report soon”, or, in the event they didn’t reply, the editor will find another referee. Nowadays with arxiv and such, there is usually no rush to actual publication as far as priority is concerned.

I’d also say, don’t take the combative mindset as suggested in the comic. Think of it more as having some fresh pairs of eyes to check your work as well as communication (if a referee misunderstood something in your paper, chances are many readers will as well).
