引力Chern-Simons与绝热极限

Gravitational Chern-Simons and the adiabatic limit

Brendan McLellan

摘要:

我们使用广义相对论中的标准方法计算了绝热度量族的引力Chern-Simons项。我们使用的事实,我们的基础三流形是一个拟正则K-接触流形在这个计算中大量。我们的关键观察是,这个几何假设正好对应于我们的三个流形上的度量张量的卡鲁扎-克莱因近似,这使我们能够将我们的问题转化为广义相对论的语言。在Guralnik、Iorio、Jackiw和Pi(2003)的论文中已经进行了类似的计算,尽管不是在绝热环境中。

英文摘要:

We compute the gravitational Chern-Simons term explicitly for an adiabatic family of metrics using standard methods in general relativity. We use the fact that our base three-manifold is a quasi-regular K-contact manifold heavily in this computation. Our key observation is that this geometric assumption corresponds exactly to a Kaluza-Klein Ansatz for the metric tensor on our three manifold, which allows us to translate our problem into the language of general relativity. Similar computations have been performed in a paper of Guralnik, Iorio, Jackiw and Pi (2003), although not in the adiabatic context.
