关于$f(R)$理论的标量-张量表示的评论
Comments on Scalar-Tensor Representation of $f(R)$ Theories
摘要:
我们提出了一个标量张量表示的$f(R)$理论与使用保角变换。在这种表示中,该模型采用具有势函数和非零动力学项的标量场的Brans-Dicke模型的形式。我们发现,由于标量场与物质系统的相互作用,相应的物质应力张量不守恒和测试粒子经历一个异常的加速。
英文摘要:
We propose a scalar-tensor representation of $f(R)$ theories with use of conformal transformations. In this representation, the model takes the form of the Brans-Dicke model with a potential function and a non-zero kinetic term for the scalar field. We show that due to interaction of the scalar field with matter systems, the corresponding matter stress tensor is not conserved and test particles experience an anomalous acceleration.
