a, IR versus μLD and μRD with VR = 10 μV. The evolution of the spectrum with the chemical potential is taken along the dashed, dashed-dotted and dotted lines in panels b, c and d, respectively. Data taken at the ↓↑ spin configuration with fixed VPG = 218 mV. b, Local conductance spectroscopy taken at gate setpoints marked by corresponding symbols in panel a. c, Conductance matrix as a function of bias and VLD, taken along the dashed blue line in panel a, that is, varying the detuning between the QDs δ = (μLD − μRD)/2 while keeping the average chemical potential \(\bar{\mu }=({\mu }_{{\rm{LD}}}+{\mu }_{{\rm{RD}}})/2\) close to 0. d, Conductance matrix as a function of bias and VLD, taken along the dotted green line in panel a, keeping the detuning between the QDs around 0. e, Conductance matrix as a function of bias and VLD, taken along the dashed-dotted pink line in panel a, keeping roughly constant non-zero detuning between the QDs. f–h, Numerically calculated G as a function of energy ω and μLD and μRD along the paths shown in panel a. All of the numerical curves assume the same parameters as those in Fig. 3, except with Δ = 23 μeV and t = 6 μeV.
