    Twisted Bilayer Magnets 
 
5. Abstract
    Recent experiments with twisted bilayer materials have provided a versatile platform for the realization of exotic phases of matter. In this talk, we are going to expand the theory of moire systems to spin systems. Starting from the brief review of twisted bilayer graphene, we develop a concrete theory of twisted bilayer magnetism. Based on the first-principles calculations of two-dimensional honeycomb magnet CrI3, we construct the generic spin models that represent a broad class of twisted bilayer magnetic systems. Using the Monte-Carlo method, we discover a variety of non-collinear magnetic order that has been overlooked in previous theoretical and experimental studies. Finally, we show that the twisted magnets can be a promising candidate for the discovery of topological magnon excitations.
