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,…
Quantum Phases in Twisted Homobilayer Transition Metal Dichalcogenides
