On Friday 7 October 2022 I had the pleasure of giving a presentation at the LPS Orsay, just south of Paris, France. Since the group there has a lot of interest in strong correlations and topology, it was a good time to present an overview of my TMD-related work from last year.
Abstract: The recent revolution in moiré materials started with the discovery of correlated insulators and superconductivity in twisted bilayer graphene. I will show that much stronger electron correlations appear in moiré bilayers of transition-metal dichalcogenides (TMDs).
After introducing the origin of flat bands in TMD moirés (including ARPES results), I will discuss theoretical predictions for a range of exotic phenomena: the amorphous Wigner-Mott electron slush; the 3/4 chiral spin liquid; and metal-insulator criticality.
