Great video! As a graphene researcher, I would say this provides an intriguing aspect for layman! Also in the field today, this even-odd effect is more pronouced as few groups found the Bernal stacked graphene exhbits also flatbands, superconductors... which previously is only found in twist graphene systems. Welcome all to join the graphene research for fantastic observations!

[lourdestorres]

I have never been so pleased by a VTuber Physicist. Then again, you are the first one I've seen. Great content mate

[田元岸]

Thank you so much for helping me understand a lil bit of BLG QDs...

[bobross]

I'm showing this to all of my students, thank you so much

[ericvilas]

Yo I just found this channel and it's really cool! Condensed matter physics explained by a VTuber is exactly what I needed in my life :D
Joined the Discord, can't wait to chat there!

Nice to see your video after a long time. Your videos are awesome. Please do upload such videos on a regular basis.

[m_obispo]

Good to see catboi physicist back! Nice content as usual ^_^

[bobfake]

typically, many people probablay say they understand material better from youtube because its the second time they get exposed to it, the first time being in class. However, i must say that i can use your videos to either step ahead of course work or touch on stuff and take informed research steps for projects in our working group in order to keep up with people ahead of me in their studies.

To sum up, gj on your explanations, probably simple enough for even laymen to grasp the basics and for students like me to recap and get a boost in studying speed. Thank you!

[juyeongjeong]

Thanks for the great video! But can you explain why bilayer graphene should have a gap opening like TMD? I don't understand because graphene has the same sublattice, unlike TMD which could give different potentials on each sublattice.

[maurizioibba]

thanks for the detailed explanation. I`m still processing, for many piece of info I have to rewind and listen over and over, but at least I start getting the full picture, magic graphene

[alexanderx]

As soon as you said coulomb force I got "no game no life" flashbacks.
😎

[fermiLiquidDrinker]

This is why more introductory textbooks need to talk about electron-electron interactions outside of the Hartree approximation

[puspitaparui]

At 8:00 min of the video, you mentioned that if inversion symmetry is broken, the band structure at the k and k' point will no longer look similar. But next you showed that breaking inversion symmetry in graphene using two different potentials at two different sublattices of graphene leads to a band gap opening, And the band structure you showed is similar at both k and k' points. So, i am a bit confused at that point.

[satyamjha_]

@9:00 i still don't get how you get a gapless band structure even after adding a mass term for a mono-layer graphene?

[ianyap]

At 8:25, this is attributed to Haldane, who showed that graphene respect time-reversal symmetry, but topological features cannot be extracted until you break this time reversal symmetry (By distinguishing these two sets of triangular atoms). One can also also add a magnetic field to break this time-reversal symmetry as well.

[Yolko]

My quantum condensed matter lecturer is really boring to watch I'm so glad of all the topics to have explained to me by a catboy it's this

[anasahmed]

i am an idiot so i didn't understand anything, but hey an anime catboi talking about physics is cool.
no jokes keep up the good work ^_^

[weldous]

wtf did u call Schrödinger? skreudinjer? OMEGALUL
