Magic-Angle Graphene Superlattices: Pablo Jarillo-Herrero

Pablo Jarillo-Herrero (MIT) presents his surprising discovery of an ultrathin material consisting of two misaligned sheets of graphene that can be easily converted from being a Mott insulator to a superconductor at the APS March Meeting 2018 in Los Angeles, CA.

Magic-Angle Graphene Superlattices: a New Platform for Strongly Correlated Physics
-------------------------------------------------
In this talk I will discuss a new platform for strongly correlated physics based on magic-angle graphene superlattices. In particular, I will show that when two graphene sheets are twisted by an angle close to the theoretically predicted ‘magic angle’, the resulting flat band structure near the Dirac point gives rise to a strongly-correlated electronic system. These flat bands exhibit half-filling insulating phases at zero magnetic field, which we show to be a Mott-like insulator arising from electrons localized in the moiré superlattice. Doping away from the Mott-like state, we achieve electrically tunable superconductivity, with many characteristics similar to cuprate superconductivity, including superconducting domes, small Fermi pockets, and strong coupling.

Thank you for recording and sharing this video.

oh boy, this is gonna be fun! =)

[@iagohernandezgonzalez1781]

As spanish really proud of this scientist .... He and his team of MIT has done a great and unexpected discovery of how can work superconductivity in High Tc not conventionals... This toy model can give us a lot of signs to finally explain how really works this kind of superconductivity....

Where could we get the nice slides?

It’s still magical

I thought Cao was the 1st author.

So what are the actual facts?

From a know-nothing on physics I read this article and found it very interesting. I also was one of the first know-nothings to hear of stemcells early 2000s. www.quantamagazine.org/how-twisted-graphene-became-the-big-thing-in-physics-20190430/?

Does en.wikipedia.org/wiki/Hofstadter%27s_butterfly show up?

Can you repeat this video with someone that speaks English well. I can only understand about 20% of what he is saying.

[@hschnabel3055]

funlovingJohn dude this is was live recording from one of the summits :-) You can probably get your hands on the presentation if you ask the support desk of Graphene-flagship.eu

[@wc2351]

Pablo's English is good enough; it must be your listening capability that is not good.

[@krystiannowakowski7980]

I got every word.

[@442277100]

Nah, his english is fine.
