论文摘要
我们对有关斧头$ f（r）$ GRAVITY的最新发展进行了紧凑的评论。 Axion场是一个弦理论，该理论源自理论粒子，是低质量粒子暗物质的理想选择。 In this review we present how a viable inflationary phenomenology and a viable late-time evolution can be described by an axion $F(R)$ gravity theory, in which the $F(R)$ gravity part can drive in a geometric way the inflationary and the late-time era, and the axion field behaves as dark matter, with its energy density $ρ_a$ behaving as a function of the scale factor as $ρ_a\sim a^{ - 3} $。我们还简要讨论了非平凡的斧头Chern-Simons耦合对$ r^2 $模型的通货膨胀现象学的影响。最后，我们简要讨论了轴突场与曲率对中子星对中子恒星的非最小耦合的影响，以及Chern-Simons Axion Gravity中的重力波的传播。
We provide a compact review on recent developments on axion $F(R)$ gravity. The axion field is a string theory originating theoretical particle that is a perfect candidate for low-mass particle dark matter. In this review we present how a viable inflationary phenomenology and a viable late-time evolution can be described by an axion $F(R)$ gravity theory, in which the $F(R)$ gravity part can drive in a geometric way the inflationary and the late-time era, and the axion field behaves as dark matter, with its energy density $ρ_a$ behaving as a function of the scale factor as $ρ_a\sim a^{-3}$. We also briefly discuss the effect of a non-trivial axion Chern-Simons coupling on the inflationary phenomenology of the $R^2$ model. Finally, we briefly discuss the effects of a non-minimal coupling of the axion field with the curvature on neutron stars, and also the propagation of gravity waves in Chern-Simons axion gravity.
