真空的正则化费米投影

On the Regularized Fermionic Projector of the Vacuum

Felix Finster

摘要:

我们构造了具有球对称正则化的费米子投影子族,它们满足分布${\mathcal{M}} P$ -积的条件。该方法是分析正则化尾部与幂律或对数标度的复合表达式中的费米投影仪。由此产生的正则化打破了洛伦兹对称性,并在光锥附近产生了费米投影仪的多层结构。剩余的自由度的正规化参数和正常化的费米子状态的后果进行了讨论。

英文摘要:

We construct families of fermionic projectors with spherically symmetric regularization, which satisfy the condition of a distributional ${\mathcal{M}} P$-product. The method is to analyze regularization tails with a power-law or logarithmic scaling in composite expressions in the fermionic projector. The resulting regularizations break the Lorentz symmetry and give rise to a multi-layer structure of the fermionic projector near the light cone. The remaining freedom for the regularization parameters and the consequences for the normalization of the fermionic states are discussed.
