Superconductivity in TBG was originally sold as "unconventional". This article reaffirms that claim by showing how it cannot be a BCS superconductor, and more.

Superconductivity in TBG was originally sold as "unconventional". This article reaffirms that claim by showing how it cannot be a BCS superconductor, and more. Very interesting.
It's worth reiterating that while graphene can have some niche uses in "the real world", the main reason that it is so highly prized within academia is that it is a superb platform for studying fundamental physics, as in this work. Maybe in the future this will lead to room-temperature superconductors or something along those lines. Maybe not. Nobody jokes about how the Higgs boson has failed to leave the lab.
- wwarner 4y agoWhenever I read about bilayer twisted graphene or topological insulators, I can’t help thinking that these are going to be the basis for next-gen transistors. Of I totally agree that understanding nature is its own goal, please raise my taxes for graphene research!
- spxtr 4y agoThey won't, but MoS_2 very well could be.
- katmannthree 4y agoWell if not it's still a nice bike chainwax additive! (/s/2)

- omnicognate 4y agoOfftopic, personal bugbear on a grumpy early morning: I have a physics degree, which is true of only a minority of HN users, and I have no idea what TBG and BCS stand for here. Using abbreviations when communicating with audiences that can't be expected to know them wastes everyone else's time to save you seconds of typing. Edit: TBG - Twisted Bilayer Graphene, BCS - Bardeen–Cooper–Schrieffer.
- ianai 4y agoThese sort of abbreviations can be basically impossible to figure out for the rest of us. Thank you.
