Research paperTheoreticalComputational MultiscaleAnalytical solution for the relaxed atomic configuration of twisted bilayer graphene including heterostrainJian Kang, Oskar Vafek2025·10.1073/pnas.2307151120·arXiv:2502.15154AbstractContinuum atomic relaxation models for twisted bilayer graphene involve minimization of the sum of intralayer elastic energy and interlayer adhesion energy. The work compares two relaxation models against published Bragg interferometry data, identifies the model with better agreement, and derives accurate closed-form expressions for relaxed twisted bilayer graphene with and without external heterostrain. The paper also analyzes the analytic structure of the solution in the complex coupling parameter and obtains the radius of convergence of the Taylor-series expansion.Read more
