What is Magic Angles in Twisted Bilayer Graphene about?

This document discusses the origin of magic angles in twisted bilayer graphene (TBG) that lead to superconductivity, revealing a continuum model that explains the appearance of perfectly flat bands at these angles. The authors identify a remarkable periodicity in the magic angles and demonstrate that the flat band wave functions can be constructed using ratios of theta functions, linking them to quantum Hall wave functions. The findings suggest that the flatness of bands at magic angles is a fundamental cha
