研究了束缚在谐振子陷阱中的费米子原子准一维量子气体的物理性质。利用均匀气体的低能性质可以用Luttinger模型精确描述的事实，我们分析了自旋-电荷分离的本质和表现形式，其中在原子的情况下，“自旋”和“电荷”分别指两种内部原子态和原子质量密度。我们讨论了必要的物理条件和实验限制可能面临的实验实现。
We investigate the physical properties of quasi-1D quantum gases of fermionic atoms confined in harmonic traps. Using the fact that for a homogeneous gas the low-energy properties are exactly described by a Luttinger model, we analyze the nature and manifestations of spin-charge separation, where in the case of atoms "spin" and "charge" refer to two internal atomic states and the atomic mass density, respectively. We discuss the necessary physical conditions and experimental limitations confronting possible experimental implementations.
