Resonance of the sample circuit in the superconducting state. Magnitude of Γ(ω) in dB (color scale) as a function of frequency and temperature for the selected gate values, VG = −34 V (a), VG = +14 V (b), VG = +24 V (c), and VG = +50 V (d). The corresponding dc resistance as a function of temperature is shown in gray solid lines (right axis)
