准二维偶极散射

Quasi-two dimensional dipolar scattering

Christopher Ticknor

摘要:

我们研究了具有一维限制的两体偶极散射。我们包括限制的影响,通过扩大这个自由度的谐振子状态。然后,我们研究所产生的多通道系统的属性。我们研究了绝热曲线作为D/l的函数,偶极和限制长度尺度的比率。当D/l < 0.34时,该体系不存在偶极势垒。我们还研究了WKB隧穿几率随D/l和散射能量的变化。这可以用来估计散射的特性。

英文摘要:

We study two body dipolar scattering with one dimension of confinement. We include the effects of confinement by expanding this degree of freedom in harmonic oscillator states. We then study the properties of the resulting multi-channel system. We study the adiabatic curves as a function of D/l, the ratio of the dipolar and confinement length scales. There is no dipolar barrier for this system when D/l < 0.34. We also study the WKB tunneling probability as a function of D/l and scattering energy. This can be used to estimate the character of the scattering.
