平坦空间中的高自旋全息

Towards higher-spin holography in flat space

Dmitry Ponomarev

摘要:

本文研究了手征平坦空间高自旋代数,它是手征高自旋理论在四维Minkowski空间中的整体对称代数。我们发现它可以被构造为Poincare代数的某个手征变形的泛包络代数,并由一组二次恒等式表示。这些身份使我们能够确定后一种代数的表示,通过类比AdS空间高自旋全息,我们解释为平坦空间单态表示。我们提供了两个明确的实现,这种单例表示-在$sl(2,\mathbb{C})$旋量和类变量的条件-以及简要讨论其属性。

英文摘要:

We study the chiral flat space higher-spin algebra, which is the global symmetry algebra of the chiral higher-spin theory in the 4d Minkowski space. We find that it can be constructed as the universal enveloping algebra of a certain chiral deformation of the Poincare algebra quotiented by a set of quadratic identities. These identities allow us to identify a representation of the latter algebra, which by analogy with the AdS space higher-spin holography, we interpret as the flat space singleton representation. We provide two explicit realisations of this singleton representation -- in terms of $sl(2,\mathbb{C})$ spinors and in terms of oscillator-like variables -- as well as briefly discuss its properties.
