Exemplary set of raw data with analysis. a Difference of currents, I ↑ − I ↓, as a function of magnetic flux density, B, and the plunger gate voltage, V P. b Magnitude of AB oscillation, M, obtained by Fourier analysis with respect to B. The arrow indicates the periodicity of the AB oscillation, ΔB. c Slice of M at ΔB (left axis; blue points) and electrical conductance through the quantum dot (right axis; black line) as a function of V P. d Difference of the AB phases, ϕ ↑ − ϕ ↓. e Transmission phase, ϕ, (red points) as a function of V P. The dashed line indicates the evolution expected from a Breit–Wigner profile based on a Lorentzian fit of G see data (c). Data points not fulfilling our quality criteria are shown as open, grey symbols
