非最小耦合暴胀的各向异性

Anisotropy in Inflation with Non-minimal Coupling

Bin Chen, Zhuang-wei Jin

摘要:

研究了一个新的各向异性暴胀模型,暴胀子场与引力场和矢量场非极小耦合。我们发现,各向异性吸引子解不仅存在于弱曲率耦合极限,而且更有趣的是,在强曲率耦合极限。我们表明,在强曲率耦合极限,从各向异性的贡献被大大抑制。

英文摘要:

We study a new anisotropic inflation model, with an inflaton field nonminimally coupled with the gravity and a vector field. We find that the anisotropic attractor solution exists not only in the weak curvature coupling limit, but more interestingly in the strong curvature coupling limit as well. We show that in the strong curvature coupling limit, the contribution from the anisotropy is greatly suppressed.
