Wigner Molecular Crystals from Multi-electron Moiré Artificial Atoms
Hongyuan Li, Ziyu Xiang, Aidan P. Reddy +10
Semiconductor moiré superlattices provide a versatile platform to engineer new quantum solids composed of artificial atoms on moiré sites. Previous studies have mostly focused on t…
Multi-moiré trilayer graphene: lattice relaxation, electronic structure, and magic angles
Charles Yang, Julian May-Mann, Ziyan Zhu +1
We systematically explore the structural and electronic properties of twisted trilayer graphene systems. In general, these systems are characterized by two twist angles, which lead…
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…
Strong-coupling topological states and phase transitions in helical trilayer graphene
Yves H. Kwan, Patrick J. Ledwith, Chiu Fan Bowen Lo +1
Magic-angle helical trilayer graphene relaxes into commensurate moiré domains, whose topological and well-isolated set of narrow bands possess ideal characteristics for realizing r…
Electronic ratchet effect in a moiré system: signatures of excitonic ferroelectricity
Zhiren Zheng, Xueqiao Wang, Ziyan Zhu +17
Electronic ferroelectricity represents a new paradigm where spontaneous symmetry breaking driven by electronic correlations, in contrast to traditional lattice-driven ferroelectric…
Diverse magnetic orders and quantum anomalous Hall effect in twisted bilayer MoTe2 and WSe2
Taige Wang, Trithep Devakul, Michael P. Zaletel +1
Twisted homobilayer transition metal dichalcogenide (TMD) offers a versatile platform for exploring band topology, interaction-driven phases, and magnetic orders. We study the inte…
