我们提出了有效自旋链模型的一般形式，用于在一维（1D）陷阱中具有任意自旋的强相互作用原子气体。特别是，对于高自旋系统，原子可以在多个散射通道中碰撞，我们发现自旋链模型的结果形式通常遵循与相互作用势相同的结构。这是适用于任何自旋、统计（玻色或费米）和限制势的统一形式。我们采用自旋链模型来揭示一维陷阱中强相互作用的自旋 1 玻色子的铁磁 (FM) 和反铁磁 (AFM) 磁序。我们进一步表明，通过添加自旋轨道耦合，FM/AFM 级数可以逐渐被破坏，最终基态表现出通用的自旋结构和与自旋轨道耦合强度无关的接触。
We present a general form of the effective spin-chain model for strongly interacting atomic gases with an arbitrary spin in the one-dimensional(1D) traps. In particular, for high-spin systems the atoms can collide in multiple scattering channels, and we find that the resulted form of spin-chain model generically follows the same structure as that of the interaction potentials. This is a unified form working for any spin, statistics (Bose or Fermi) and confinement potentials. We adopt the spin-chain model to reveal both the ferromagnetic(FM) and anti-ferromagnetic(AFM) magnetic orders for strongly interacting spin-1 bosons in 1D traps. We further show that by adding the spin-orbit coupling, the FM/AFM orders can be gradually destroyed and eventually the ground state exhibits universal spin structure and contacts that are independent of the strength of spin-orbit coupling.
