Figure 6
(a,b) Display the long-time evolution of the wave packet in a nonlinear system in the n−t and in the x−t planes, respectively. The system parameters are the same as in Fig. 1 except for the nonlinearty parameter used is g = 1. The initial condition is given by Eq. (5) with a 0 = 0.15, w x = 10 and w = 100.
