关于含费米子的广义Einstein-Cartan Action

On the Generalized Einstein-Cartan Action with Fermions

Meriem-Hadjer Lagraa, Mohammed Lagraa

摘要:

从[1]中提出的广义Einstein作用量所表现出的自由度出发,我们证明了我们可以构造出与费米子物质耦合的标准有效Einstein-Cartan作用量,而不需要通常的电流-电流相互作用,从而得到一个既不依赖于Immirzi参数也不依赖于挠率的有效作用量。这就建立了爱因斯坦-嘉当理论和与费米子物质最小耦合的广义相对论理论之间的等价性。

英文摘要:

From the freedom exhibited by the generalized Einstein action proposed in [1], we show that we can construct the standard effective Einstein-Cartan action coupled to the fermionic matter without the usual current-current interaction and therefore an effective action which does not depend neither on the Immirzi parameter nor on the torsion. This establishes the equivalence between the Einstein-Cartan theory and the theory of the general relativity minimally coupled to the fermionic matter.
