Figure 3. The quantum evolution of the amplitude of the BEC matter-wave field versus the scaled time τ; the BEC part is the rapidly changing part. (a) The case of the absence of impurities with the number of the BEC n0 = 105 and the coupling ratio κ = zero. (b) The case of the presence of impurities with the number of the BEC n0 = 105, the number of impurities N = 20, and the coupling ratio κ = 0.005. |
