Offtopic, 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.

These sort of abbreviations can be basically impossible to figure out for the rest of us. Thank you.
