局域原子波包的构造
Construction of localized atomic wave packets
摘要：
结果表明，在低维玻色-爱因斯坦凝聚体（BEC）中，通过随时间改变陷阱频率，可以在规则简谐陷阱中产生高度局域化的孤子。在这种阱中捕获的BEC可以有效地用于构造发射相干原子波包的脉冲原子激光器。它也表明，一个完全控制的时空动力学的孤子。这些孤子的动力学进行了比较，在BEC中的陷阱频率是恒定的。
英文摘要：
It is shown that highly localized solitons can be created in lower dimensional Bose-Einstein condensates (BEC), trapped in a regular harmonic trap, by temporally varying the trap frequency. A BEC trapped in such a trap can be effectively used to construct a pulsed atomic laser emitting coherent atomic wave packets. It is also shown that one has complete control over the spatio-temporal dynamics of the solitons. The dynamics of these solitons are compared with those constructed in a BEC where the trap frequency is constant.
