Pseudospin stiffness (top), antiferromagnetic coupling J and pseudospin easy-plane anisotropy λ (bottom) as a function of the twist angle θ for different values of the gate screening distance d for dielectric constant ϵ = 9.5. All curves are computed using the analytic expressions provided in the Supplementary Materials using the band renormalization scheme of (68).
