Resolving Intervalley Gaps and Many-Body Resonances in Moiré Superconductor
Hyunjin Kim, Gautam Rai, Lorenzo Crippa +15
Magic-angle twisted multilayer graphene stands out as a highly tunable class of moiré materials that exhibit strong electronic correlations and robust superconductivity. However, u…
