Abstract

The motion of a dark soliton in one-dimensional Bose-Einstein condensates with an expulsive parabolic potential is investigated.Furthermore,the dynamics of dark soliton and the interaction between two dark solitons are discussed in detail by numerical simulation.The results show that the motion of dark soliton is periodical,and the interaction between two dark solitons exhibits to collide each other periodically.As the separation between two dark solitons becomes shorter,the periodical colliding is shrinking and the period of the colliding action is shorter.It is meaning for us to understand the dynamics of microphysical field.

We present two families of analytical solutions of the one-dimensional nonlinear Schr\"odinger equation, which describe the dynamics of bright and dark solitons in Bose-Einstein condensates (BECs) with the time-dependent interatomic interaction in an expulsive parabolic and complex potential. We also demonstrate that the lifetime of both a bright soliton and a dark soliton in BECs can be extended by reducing both the ratio of the axial oscillation frequency to radial oscillation frequency and the loss of atoms. It is interesting that a train of bright solitons may be excited with a strong enough background. An experimental protocol is further designed for observing this phenomenon.

Evolution of a dark soliton in a parabolic potential: Application to Bose-Einstein condensates

Valeriy A. Brazhnyi, V. V. Konotop

Evolution of a dark soliton in a one-dimensional Bose-Einstein condensate trapped by a harmonic potential is studied analytically and numerically. In the case of a deep soliton, main characteristics of its motion such as frequency and amplitude of oscillations are calculated by means of the perturbation theory which in the leading order results in a Newtonian dynamics, corrections to which are computed as well.

Effects of external magnetic trap on two dark solitons of a two-component Bose-Einstein condensate

李宏 Hong Li, D. N Wang

Two dark solitons are considered in a two-component Bose-Einstein condensate with an external magnetic trap, and effects of the trap potential on their dynamics are investigated by the numerical simulation.The results show that the dark solitons attract, collide and repel periodically in two components as time changes, the time period depends strictly on the initial condition and the potential, and there are obvious self-trapping effects on the two dark solitons.

Soliton Solutions in Bose–Einstein Condensates with Time-Dependent Atomic Scattering Length in an Expulsive Parabolic Potential

Zhang Jie-Fang, Yang Qin

We present both the bright and dark solitons of Bose–Einstein condensates with a time-dependent atomic scattering length in an expulsive parabolic potential. As a discussed example, we select the experimental parameter, i.e. the Feshbach-managed nonlinear coefficient reading a ( t ) = g 0 exp(λ t ), and obtain the results which can be recovered in the literature [Phys. Rev. Lett. 94 (2005) 050402].

Dynamics of Bright/Dark Solitons in Bose–Einstein Condensates with Time-Dependent Scattering Length and External Potential

Ai‐Xia Zhang, Xue Ju-Kui

We present an analytical study on the dynamics of bright and dark solitons in Bose–Einstein condensates with time-varying atomic scattering length in a time-varying external parabolic potential. A set of exact soliton solutions of the one-dimensional Gross–Pitaevskii equation are obtained, including fundamental bright solitons, higher-order bright solitons, and dark solitons. The results show that the soliton's parameters (amplitude, width, and period) can be changed in a controllable manner by changing the scattering length and external potential. This may be helpful to design experiments.
