一维囚禁偶极气体中的Super-Tonks-Girardeau区

Super-Tonks-Girardeau regime in trapped one-dimensional dipolar gases

G. E. Astrakharchik, Yu. E. Lozovik

摘要:

本文讨论了零温条件下准一维玻色子系统中超Tonks-Girardeau气体的可能特征。我们提供的最低压缩模式的频率估计,并将其与使用谐波方法在高密度区得出的分析结果进行比较。我们构造了玻色子、费米子和玻色-费米子混合物的一维偶极系统基态波函数的精确映射,并得出了零温下局域性质和能量相同的结论.在何种程度上的偶极电位可以治疗长程或短程的问题进行了讨论.

英文摘要:

Possible signatures of a super-Tonks-Girardeau gas in bosonic systems of trapped quasi-one-dimensional dipoles are discussed at zero temperature. We provide estimation of the frequency of the lowest compressional mode and compare it to analytical results derived using harmonic approach in the high density regime. We construct an exact mapping of the ground-state wave function of one-dimensional dipolar system of bosons, fermions and Bose-Fermi mixture and conclude that local properties and energy are the same at zero temperature. A question of to which extent the dipolar potential can be treated long- or short- range is discussed.
