硬壁阱中p波相互作用下一维自旋极化费米子原子气体中的亮、暗孤波

Bright and dark solitary waves in a one-dimensional spin-polarized gas of fermionic atoms with p-wave interactions in a hard-wall trap

M. D. Girardeau, E. M. Wright

摘要:

在本文中,我们阐明的物理基础的事实,即明亮和黑暗的孤立波可以出现在一个一维自旋极化的费米子原子的气体与吸引的三维p波相互作用的硬壁陷阱。这是可能的,因为一维费米子系统可以映射到由Lieb-Liniger模型描述的玻色子系统,具有排斥或吸引的δ函数相互作用,可以支持孤立波。

英文摘要:

In this paper we elucidate the physics underlying the fact that both bright and dark solitary waves can arise in a one-dimensional spin-polarized gas of fermionic atoms with attractive three-dimensional p-wave interactions in a hard-wall trap. This is possible since the one-dimensional fermion system can be mapped to a system of bosons described by the Lieb-Liniger model with either repulsive or attractive delta-function interactions which can support solitary waves.
