修正引力理论中Wheeler DeWitt方程的宇宙学常数提取

Extracting the Cosmological Constant from the Wheeler DeWitt Equation in a Modified Gravity Theory

Remo Garattini

摘要:

我们讨论了如何提取信息的宇宙学常数从惠勒-德威特方程,被认为是一个特征值的Sturm-Liouville问题。对f(R)理论的推广进行了研究。该方程近似为一个循环的帮助下,高斯试探波泛函的变分方法。我们使用zeta函数正则化来处理分歧。引入了一个重整化过程和一个重整化群方程来消除无穷大。

英文摘要:

We discuss how to extract information about the cosmological constant from the Wheeler-DeWitt equation, considered as an eigenvalue of a Sturm-Liouville problem. A generalization to a f(R)theory is taken under examination. The equation is approximated to one loop with the help of a variational approach with Gaussian trial wave functionals. We use a zeta function regularization to handle with divergences. A renormalization procedure is introduced to remove the infinities together with a renormalization group equation.
