用旋量表示的圈引力

Loop gravity in terms of spinors

Etera R. Livine, Johannes Tambornino

摘要:

我们表明,圈引力可以同样很好地制定在旋变量(而不是常用的组变量),最近已被证明提供了一个直接的自旋网络状态和离散几何之间的联系。这导致在一个新的,统一的等价制定的理论上的广义巴格曼空间。由于积分组交换为简单的积分在复杂的平面上,我们希望这种形式主义是有用的,有效地组织实际计算。

英文摘要:

We show that loop gravity can equally well be formulated in in terms of spinorial variables (instead of the group variables which are commonly used), which have recently been shown to provide a direct link between spin network states and discrete geometries. This results in a new, unitarily equivalent formulation of the theory on a generalized Bargmann space. Since integrals over the group are exchanged for straightforward integrals over the complex plane we expect this formalism to be useful to efficiently organize practical calculations.
