我们报道了在引力场的影响下，BEC在拓扑相印迹过程中的行为。当引力场垂直于涡旋线时，系统不再是轴对称的，涡旋也不总是稳定的。我们数值求解了含时的Gross-Pitaevskii方程，发现微调反转时间可以产生稳定的涡旋。
We report behavior of BEC during topological phase imprinting under the influence of a gravitational field. When the gravitational field is perpendicular to the vortex line as in the experiments, the system is no longer axisymmetric and the vortex is not always stable. We solved the time-dependent Gross-Pitaevskii equation numerically and found that a stable vortex is produced by fine-tuning the field reverse time.
