The file: "Transmission_Field.opju" contains the magnetic field dependence of the transmittance measured at 950 GHz and with different gate voltages corresponding to different Fermi level positions. Also given is the gate voltage dependence of the cyclotron effective mass which corresponds to the linear electron spectrum in the HgTe quantum well with critical thickness. Transmittance oscillations measured at 1019 GHz and atVg = 9V together with SdH oscillations of capacitance, are obtained subtracting the smooth part of the transmittance |t |^2. The theory curve is calculated using Eqs. (1) and (3) of the main text. The phase of dynamic SdH oscillations is flipped across the node.

The file "Nodes_in_Transmission.opju" showsthe imaginary vs real parts of the transmission amplitude t . The tunable nodes arise when t and its small correction δt are perpendicular to each other on the complex plane. Also shown are the magnetic field dependences of sin(πω/ωc ) (universal nodes) and of calculated transmittance SdH oscillations; and the graphical solution of Eq. (4) of the main paper determining the tunable nodes in transmittance.

The file "Phase_SdH.opju" contains the magnetic field dependences of the amplitude of the parallel transmittance |t_p| and its phase ϕ, respectively, measured at 360 GHz. Oscillations of the parallel transmittance amplitude and its phase are given in 1/B scale, the smooth parts in |t_p|^2 and ϕ were subtracted. Black thick lines are experimental data, red thin lines are fits based on Eqs. (1) and (3) of the main paper.
