Probe-polarization-dependent quantum beats. a θpr-resolved DT with offset. θpu is fixed at 160°. Analyses are performed on the right side of the vertical gray line. b, c Comparison of beating amplitude obtained from theory (b) and experiments (c). Solid line in b is same as that in Fig. 4c. Gray (green) area represents the region I (II). The error bars represent 95% confidence intervals for the fitting parameters
