Multiple flat bands and topological Hofstadter butterfly in twisted bilayer graphene close to the second magic angle

Moiré superlattices in two-dimensional van der Waals heterostructures provide an efficient way to engineer electron band properties. The recent discovery of exotic quantum phases and their interplay in twisted bilayer graphene (tBLG) has made this moiré system one of the most renowned condensed matt...
