Quantum-Geometric Design of Lattice Generalized Landau Levels
Bohao Li, Fengcheng Wu
We design lattice models with tailored quantum geometry, including generalized Landau levels (LLs) satisfying the integrated trace condition and higher-Chern bands with ideal quant…
Abelian and non-Abelian fractionalized states in twisted MoTe: A generalized Landau-level theory
Bohao Li, Yunze Ouyang, Fengcheng Wu
Fractional Chern insulators are lattice analogs of fractional quantum Hall states that realize fractionalized quasiparticles without an external magnetic field. A key strategy to u…
Observation of a Reconstructed Chern Insulator in Twisted Bilayer MoTe2
Min Wu, Lingxiao Li, Yunze Ouyang +12
Twisted bilayer MoTe2 is a prototypical moire material in which long-wavelength superlattices amplify electron correlations, enabling a wealth of emergent quantum phases. To date,…
Characterization of fractional Chern insulator quasiparticles in twisted homobilayer MoTe
