一维自旋极化费米气体在光晶格中的碰撞

Collision of one dimensional (1D) spin polarized Fermi gases in an optical lattice

J. Kajala, F. Massel, And P. Törmä

摘要:

本文分析了两个自旋极化相反的费米子原子云碰撞的动力学行为。利用时间演化块抽取(TEBD)方法,模拟了格子中两个一维云团的碰撞。在吸引和排斥相互作用之间的碰撞行为中存在对称性。我们分析了在碰撞区域的对形成动力学,提供了一个简单的两个网站模型的对形成机制的定量分析。

英文摘要:

In this work we analyze the dynamical behavior of the collision between two clouds of fermionic atoms with opposite spin polarization. By means of the time-evolving block decimation (TEBD) numerical method, we simulate the collision of two one-dimensional clouds in a lattice. There is a symmetry in the collision behaviour between the attractive and repulsive interactions. We analyze the pair formation dynamics in the collision region, providing a quantitative analysis of the pair formation mechanism in terms of a simple two-site model.
