标题： Dark Matter in logarithmic $F(R)$ gravity

摘要： 对对数修正的$R^2$型$F(R)$引力进行了研究，作为具有量子修正的修改引力理论的原型模型。 通过辅助场方法，该模型由带有标量子场的一般相对论描述。 标量子场可以在原始暴胀时期被识别为暴胀子。 在暗能量时代，它也是暗物质候选者之一。 发现参数的广泛范围与当前宇宙微波背景涨落、暗能量和暗物质的观测结果一致。 显示英文摘要

摘要： The logarithmic $R^2$-corrected $F(R)$ gravity is investigated as a prototype model of modified gravity theories with quantum corrections. By using the auxiliary field method, the model is described by the general relativity with a scalaron field. The scalaron field can be identified as an inflaton at the primordial inflation era. It is also one of the dark matter candidates in the dark energy era. It is found that a wide range of the parameters is consistent with the current observations of CMB fluctuations, dark energy and dark matter.
