Low frequency measurements. a Conductance through the QPC as a function of the QPC gate voltage for the three filling factors ν = 3 (red), ν = 4/3 (blue) and ν = 2/3 (yellow). The values of the QPC gate voltage used for noise measurements are shown by a colored disk (ν = 3), square (ν = 4/3) and diamond (ν = 2/3). b Measurements of ΔS33(f = 0, Vdc) normalized by the factor D(1 − D). Dashed lines represent plots of Eq. (1) using q = e, \(g = \frac{{e^2}}{h}\) at ν = 3, q = e/3, \(g = \frac{{e^2}}{{3h}}\) at ν = 4/3 and q = e/3, \(g = \frac{{2e^2}}{{3h}}\) at ν = 2/3
