FIG. 1.

The curves of vs from in Eq. (10) for (a) , (b) , (c) , and (d) . The other parameters are given by Eq. (11). Hereafter, all of the physical quantities are dimensionless.

FIG. 2.

The boundaries between the regular and chaotic regions for and . Areas marked by A, B, and C are the chaotic, low-chaoticity, and high-chaoticity regions, respectively, and the others are regular regions. (a) The previous chaotic regions given by Eq. (12). (b) Our chaotic regions derived from and , which agree with Fig. 1(d).

FIG. 4.

The boundaries between the regular and chaotic regions for (a) and (b) . Areas marked by B are low-chaoticity regions and areas marked by C are high-chaoticity regions, and the others are regular regions.

FIG. 5.

The time evolutions of for the parameters , , , , and [(a) and (d)] of the regular region, [(b) and (e)] of the low-chaoticity region, and [(c) and (f)] of the high-chaoticity region. [(a)–(c)] Starting from , namely, the atoms initially distribute in the two wells with the same probability. [(d)–(f)] Starting from , namely, the atoms initially concentrate in one well approximately.
