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,…
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…
Magic continuum in multi-moiré twisted trilayer graphene
Li-Qiao Xia, Aviram Uri, Jiaojie Yan +10
Moiré lattices provide a highly tunable platform for exploring the interplay between electronic correlations and band topology. Introducing a second moiré pattern extends this para…
de Haas-van Alphen spectroscopy and fractional quantization of magnetic-breakdown orbits in moiré graphene
Matan Bocarsly, Matan Uzan, Indranil Roy +12
Quantum oscillations originating from the quantization of the electron cyclotron orbits provide ultrasensitive diagnostics of electron bands and interactions in novel materials. We…
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…
Magic-angle helical trilayer graphene
Trithep Devakul, Patrick J. Ledwith, Li-Qiao Xia +4
We propose helical trilayer graphene (HTG), a helical structure featuring identical rotation angles between three consecutive layers of graphene, as a unique a…
