Spinor Condensates in Magnetic Fields

旋量凝聚体具有旋转对称性，反映了塞曼简并流形和各向同性S波原子-原子相互作用中基态原子的球状性质。在真实的实验室环境中，非零磁(B-).eld不可避免地破坏了这种对称性，并导致不同塞曼状态的不同能级移动，从而深刻地改变了凝聚态的性质。这一提议集中在磁场中旋量凝聚的理论研究上。主要的科学目标是推进原子量子气体的前沿，特别是旋量凝聚态的物理学，它具有独立控制运动和内部自由度的能力，是设计非经典原子态和大规模原子-原子纠缠的潜在候选者。

Spinor condensates possess rotational symmetry reflecting the spherical nature of ground stateatoms in Zeeman degenerate manifolds and isotropic s-wave atom-atom interactions. A nonvanishing magnetic (B-) .eld, unavoidable in real laboratory situations, breaks this symmetryand causes different level shifts for different Zeeman states, profoundly changing condensateproperties. This proposal concentrates on theoretical studies of spinor condensates in magneticfields. The primary scientific objective is to advance the frontier of atomic quantum gases, especially the physics of spinor condensates, which with the ability of independent control for themotional and internal degrees of freedom, are promising candidates for engineering nonclassicalatomic states and massive atom-atom entanglement.
