Perturbative analytic expressions for dispersion and scattering rates of Hubbard-band and Dirac excitations are derived in the topological heavy-fermion model for twisted bilayer graphene.
(S33) and (S34), we proved that at low temperature, only the Γ 1 ⊕Γ 2 celectrons acquire a dynamical self-energy at orderj∼J 2 due to the local-moment fluctuations offelectrons
