Quantized Transport through a Supermoiré Chern Mosaic
Li-Qiao Xia, Aviram Uri, Zachary W. Gomez +8
Magic-angle helical trilayer graphene---three graphene layers sequentially twisted in the same direction by ---relaxes into a mosaic of domains that, at zero field,…
Mesoscopic transport in a Chern mosaic
Sayak Bhattacharjee, Julian May-Mann, Yves H. Kwan +2
We analyze mesoscopic electronic transport in a Chern mosaic: a regular pattern of domains whose electronic bands carry differing local Chern numbers. An example platform where a C…
Electrically controllable valence-conduction band reversals in helical trilayer graphene
Matan Bocarsly, Indranil Roy, Weifeng Zhi +11
In moiré graphene systems, electronic interactions lift spin and valley degeneracies, leading to symmetry-broken ground states. In helical trilayer graphene (HTG), we uncover a dis…
Helical trilayer graphene: a moiré platform for strongly-interacting topological bands
Li-Qiao Xia, Sergio C. de la Barrera, Aviram Uri +9
Quantum geometry of electronic wavefunctions results in fascinating topological phenomena. A prominent example is the intrinsic anomalous Hall effect (AHE) in which a Hall voltage…
Spin skyrmion gaps as signatures of strong-coupling insulators in magic-angle twisted bilayer graphene
Jiachen Yu, Benjamin A. Foutty, Yves H. Kwan +6
The flat electronic bands in magic-angle twisted bilayer graphene (MATBG) host a variety of correlated insulating ground states, many of which are predicted to support charged exci…
One-Dimensional Luttinger Liquids in a Two-Dimensional Moiré Lattice
Pengjie Wang, Guo Yu, Yves H. Kwan +13
The Luttinger liquid (LL) model of one-dimensional (1D) electronic systems provides a powerful tool for understanding strongly correlated physics including phenomena such as spin-c…
