Weak localization is reported for the first time in twisted bilayer graphene, with extracted phase coherence and intervalley scattering lengths indicating electron-electron dephasing and point-defect intervalley scattering.
Derives perturbative expressions for layer-resolved in-plane displacements from continuum elasticity in moiré heterobilayers and predicts a buckling instability near alignment driven by compressive strain.
