a Oscillations of dimensionless conductivity as a function of dimensionless period index. The vertical axis is the oscillating conductivity divided by the product of \({G}_{0}=\frac{2{e}^{2}}{h}\) and kFrkFzℓBΩ−2e−Ω/π. The horizontal axis represents \(\Omega ={\ell }_{B}^{-2}{\left(\frac{\partial A}{\partial {k}_{z}}\right)}^{-1}d\). The solid blue lines represents αsin(Ω − ϕ). Save for the first oscillation, in all samples, the data matches the sine fit, with α ≈ 1 and ϕ ≈ 0.15π. b Same for Hall conductivity. A similar fit matches the data with an α, which is twice larger and a ϕ, which is shifted by  − π/2.
