受驱动光晶格中玻色-爱因斯坦凝聚体的稳定性:弱横向约束与紧横向约束的交叉

Stability of a Bose-Einstein condensate in a driven optical lattice: Crossover between weak and tight transverse confinement

Sayan Choudhury, Erich J. Mueller

摘要:

研究了横向约束对一维或二维正方晶格中玻色-爱因斯坦凝聚体稳定性的影响。我们从两粒子碰撞计算衰变率。我们预测,如果横向约束超过一个临界值,那么,对于适当的振动频率,凝聚体是稳定的,对散射到横向方向。

英文摘要:

We explore the effect of transverse confinement on the stability of a Bose-Einstein condensate (BEC) loaded in a shaken one-dimensional or two-dimensional square lattice. We calculate the decay rate from two-particle collisions. We predict that if the transverse confinement exceeds a critical value, then, for appropriate shaking frequencies, the condensate is stable against scattering into transverse directions.
