摘要

我们计算了夸克和胶子在小x的自旋轨道相关性，结果表明，即使在非极化或无自旋的强子和原子核中，单个部分子的螺旋和轨道角动量也是强烈反对齐的。结合彩色玻璃凝聚态中的胶子是线性极化的这一事实，我们的发现表明，单个胶子的螺旋度和轨道角动量在量子力学意义上是最大纠缠的。

Spin-orbit entanglement in the Color Glass Condensate

We compute the spin-orbit correlations of quarks and gluons at small-x and show that the helicity and the orbital angular momentum of individual partons are strongly anti-aligned even in unpolarized or spinless hadrons and nuclei. Combined with the fact that gluons in the Color Glass Condensate are linearly polarized, our finding indicates that the helicity and the orbital angular momentum of single gluons are maximally entangled in a quantum mechanical sense.
