SU(3)费米气体的多体关联

Multi-body correlations in SU(3) Fermi gases

Hiroyuki Tajima, Pascal Naidon

摘要:

研究了三组分原子费米气体中的强耦合效应。它是模拟量子色动力学(QCD)的一个很有前途的候选者,而且,在这个系统中,各种现象的出现,如色超流性和Efimov效应是预期的。本文利用多体$T$ -矩阵近似(TMA)和带介质修正的Skorniakov-Ter-Martirosian(STM)方程研究了两体和三体关联的影响。我们研究了有限温度和化学势对三聚体在幺正极限的超流临界点结合能的影响。

英文摘要:

We investigate strong-coupling effects in a three-component atomic Fermi gas. It is a promising candidate for simulating quantum chromodynamics (QCD), and furthermore, the emergence of various phenomena such as color superfluidity and Efimov effect are anticipated in this system. In this paper, we study the effects of two-body and three-body correlations by means of the many-body $T$-matrix approximation (TMA) as well as the Skorniakov-Ter-Martirosian (STM) equation with medium corrections. We investigate the effects of finite temperature and chemical potential on the trimer binding energy at the superfluid critical point of the unitarity limit.
