修正Brans-Dicke理论中的虫洞解

Wormhole Solutions in Modified Brans-Dicke Theory

Eleftherios Papantonopoulos, Christoforos Vlachos

摘要:

本文考虑一个修正的Brans-Dicke理论,其中除了通常的Brans-Dicke参数外,还出现了一个新的量纲参数,它修正了与引力耦合的标量场的动力学项。求解耦合的Einstein-Klein-Gordon方程,我们找到了新的球对称解。根据参数的选择,这些解决方案减少到史瓦西解的广义相对论,他们给新的虫洞解决方案,这取决于新的参数。

英文摘要:

We consider a modified Brans-Dicke theory in which except the usual Brans-Dicke parameter a new dimensionful parameter appears which modifies the kinetic term of the scalar field coupled to gravity. Solving the coupled Einstein-Klein-Gordon equations we find new spherically symmetric solutions. Depending on the choices of the parameters these solutions reduce to the Schwarzschild solution of General Relativity and they give new wormhole solutions which depend on the new parameter.
