a, Single-particle density of states (DOS) calculated for θ = 1.08° as a function of ν and D, following the model described in the text. b, Calculated single particle gaps at ν = 0, + 4 (left axis) as a function of interlayer potential, δ. Bandwidth of the conduction band, W (right axis). The bandwidth does not vary widely over our this range of δ. c, W calculated as function of θ for δ = − 40 meV. W does not change substantially for 0.85∘ < θ < 1. 1∘. d, Experimentally measured energy gaps of ν = 0, + 2, + 4 as a function of D in device D1 (θ = 1.08∘). The single particle gaps at ν = 0, + 4 are qualitatively consistent with the predictions in b. A CI gap at ν = + 2 only emerges over a finite range of D > 0.
