Figure 4

For the same initial state in Fig. 3, the charge-conjugation operation is performed at the mid-point (t=4). (a) Time-dependent probability distribution in the momentum space. Similar to the time-reversal operation, right after the charge-conjugation operation at t=4, the momentum p is reversed to −p, which makes the discontinuity at the evolution of the picture. However, the momentum-space Zitterbewegung fades away, which is clearly different from the result of the time-reversal operation. (b) Probability distributions in the momentum space at various times t=0, 3, 5 and 8 from bottom to top. (c) Time-dependent probability distribution in the position space. Although the charge-conjugation has changed the internal components of the Majorana spinor (see Supplementary Fig. 1), the trajectory of the Majorana particle is not affected by the charge-conjugation operation. (d) The same as b in the real space. The corresponding data points are marked by blue dashed lines. The error bars in a and c come from the same method to those in Fig. 3.
