Strain-induced square moire superlattices in graphene exhibit narrow bands and split Van Hove singularities reproduced by a continuum model under twist-strain conditions that minimize elastic energy.
Zero-point energy corrections from quantum fluctuations destabilize the classical honeycomb bilayer Wigner crystal and stabilize the 30-degree quasicrystalline state over a broad parameter range.
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.
