无旋转的旋转泡沫

Spin Foams Without Spins

Jeff Hnybida

摘要:

我们将离散SU(2)规范理论的自旋泡沫表示为顶点振幅的乘积,每个顶点振幅是边界图的自旋网络生成函数。在这样做时,对旋转进行求和。每个n-价节点的边界数据显着减少相对于本地规范不变性,并有一个明确的几何解释为一个框架的多面体的固定总面积。最后,自旋的总和交易的轮廓积分简单的极点和再耦合理论是避免使用生成函数。

英文摘要:

We formulate the spin foam representation of discrete SU(2) gauge theory as a product of vertex amplitudes each of which is the spin network generating function of the boundary graph dual to the vertex. In doing so the sums over spins have been carried out. The boundary data of each n-valent node is explicitly reduced with respect to the local gauge invariance and has a manifest geometrical interpretation as a framed polyhedron of fixed total area. Ultimately, sums over spins are traded for contour integrals over simple poles and recoupling theory is avoided using generating functions.
