We numerically analyze chaos and diffusion in experimentally-relevant models of twisted bilayer graphene. Our results indicate that finite systems at both commensurate and incommensurate rotation angles exhibit chaos. We compute the Thouless energy of the system at intermediate twist angles to further understand the diffusive processes associated with the chaotic nature of the spectrum. We find that the mean free path of the non-interacting electrons scales with the system size, which is consistent with diffusive processes caused by border-induced scattering. In summary, our results show the role of borders as a experimentally relevant single-particle scattering mechanism, which is much stronger than in single-layer graphene and induces chaos and diffusion regardless of the rotation angle and the lattice commensurability.
