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…
Intraband collective excitations in fractional Chern insulators are dark
Tobias M. R. Wolf, Yung-Chun Chao, Allan H. MacDonald +1
The low-energy collective excitations of semiconductors and insulators often couple strongly to light, allowing them to be probed optically. We argue here that in fractional Chern…
