Spontaneous Twirls and Structural Frustration in Moiré Materials
Jingtian Shi, Gaurav Chaudhary, Allan H. MacDonald +1
Structural twirls form spontaneously in the domain wall networks of some moiré materials. We show that in heterobilayers, neighboring twirl chiralities tend to anti-align, forming…

Independently Tunable Flat Bands and Correlations in a Graphene Double Moiré System
Yimeng Wang, Jihang Zhu, G. William Burg +6
We report on a double moiré system consisting of four graphene layers, where the top and bottom pairs form small-twist-angle bilayer graphene, and the middle interface has a large…
