最近具有吸引相互作用的超冷原子的玻色-爱因斯坦凝聚使我们考虑了在任意三维简谐陷阱中探索其基态稳定性的可能性。我们通过平均场Gross-Pitaevskii方程的完整数值解对临界原子数进行了定量分析。得到了从三维到二维和一维的特征极限，无论是在完全柱对称下，还是在变形对称下。
The recent Bose-Einstein condensation of ultracold atoms with attractive interactions led us to consider the possibility of probing the stability of its ground state in arbitrary three-dimensional harmonic traps. We performed a quantitative analysis of the critical number of atoms through a full numerical solution of the mean-field Gross-Pitaevskii equation. Characteristic limits are obtained for reductions from three to two and one dimensions, in perfect cylindrical symmetries as well as in deformed ones.
