Fig. 3: Temperature dependence of φ0 and η: theory and experiment.
a Computed temperature dependence of the (sign changed) anomalous phase shift φ0 for a Zeeman parameter of λZ = − 0.40 (which would correspond to By = − 100 mT for g-factor ∣g∣ = 12). We assume Tc = 2.0 K as in the experiments. Inset: full-range φ0(T) graph plotted for T up to T = Tc. b Computed temperature dependence of the supercurrent diode rectification efficiency − η for the same parameters as in a. Inset: full-range − η(T) graph up to T = Tc. c Measured Δφ0 (as defined in the text) at Vg = 1.0 V and By = − 100 mT, plotted as a function of temperature. d Temperature dependence of dφ0/dVg (as defined in the text) at By = 50 mT. For ease of comparison, all main graphs are plotted up to T = 0.8 K, the highest temperature for which Δφ0 and dφ0/dVg was measurable.
