AI总结:

本文提出了一种三维量子反常流体的广义GMP代数框架,通过非交换几何和拓扑BF+BB理论的关联,揭示了其几何和拓扑特性。

摘要:

我们发展了一个几何框架,用于在强三形式背景场存在下三维量子反常流体(准弦)的几何框架。在强场 regime 中,快速内部动力学被冻结,低能动力学由由矢量和张量坐标组成的广义引导中心变量支配。我们证明这些引导中心变量遵循非交换几何,从而导致由投影密度算子产生的三维GMP代数的广义化。此外,我们将该代数与拓扑BF+BB理论的规范量子化联系起来,其等级被确定为Dixmier-Douady不变量。我们的结果澄清了不可压缩量子反常型相的结构及其在三维空间中的几何和拓扑特征。

英文摘要:

We develop a geometric framework for three-dimensional quantum Hall fluids of extended objects (quasi-strings) in the presence of a strong three-form background field associated with a bundle gerbe. In the strong-field regime, fast internal dynamics is frozen and the low-energy kinematics is governed by generalized guiding-center variables consisting of vectorial and tensorial coordinates. We show that these guiding-center variables obey a noncommutative geometry giving rise to a three-dimensional generalization of the Girvin-MacDonald-Platzman (GMP) algebra for projected density operators. Moreover, we relate this algebra to the canonical quantization of a topological BF+BB theory whose level is identified with the Dixmier-Douady invariant. Our results clarify the structure of incompressible quantum Hall-type phases and their geometric and topological features in three spatial dimensions.
