某些特殊量子场论中的真空能

Vacuum energy in some particular quantum field theories

Renata Jora

摘要:

研究了一类具有相同数量的反对易场变量和对易场变量的量子场论的性质,最常见的例子是超对称模型。基于配分函数的标度性质,我们发现这些理论的量子能量动量张量与配分有关,因而真空能量等于零。

英文摘要:

We study the properties of a class of quantum field theories endowed with an equal number of anti commuting and commuting field variables, the most common example being the supersymmetric models. Based on the scaling properties of the partition function we find that these theories have the quantum energy momentum tensor associated to dilatations and thus the vacuum energy equal to zero.
