Chern-Simons修正引力理论中的Ricci暗能量

Ricci dark energy in Chern-Simons modified gravity

J. G. Silva, A. F. Santos

摘要:

在本文中,我们考虑了在动态Chern-Simons修正引力下宇宙的能量密度与Ricci标量曲率成正比的Ricci暗能量模型.我们表明,在这种情况下,尺度因子的演变是类似的,所显示的修改Chaubergin气体。

英文摘要:

In this work, we have considered the Ricci dark energy model, where the energy density of the universe is proportional to the Ricci scalar curvature, in the dynamic Chern-Simons modified gravity. We show that in this context the evolution of the scale factor is similar to that displayed by the modified Chaplygin gas.
