论文摘要

在本文中,我们想弄清楚在存在恒定滚动条件下,在恒定滚动条件下,在存在超级倾斜的情况下,标量和矢量场之间的耦合,$ f^2(ϕ)f _ {μν} f^{μLν} f^{μNν} $。结果,在这种情况下,一些新颖的各向异性通货膨胀解决方案与幂律一般。此外,这些解决方案在数值上被证实是有吸引力的,与对霍金宇宙无头发猜想的预测相反。

In this paper, we would like to figure out whether a k-inflation model admits the Bianchi type I metric as its inflationary solution under a constant-roll condition in the presence of the supergravity motivated coupling between scalar and vector fields, $f^2(ϕ)F_{μν}F^{μν}$. As a result, some novel anisotropic inflationary solutions are shown to appear along with a power-law one in this scenario. Furthermore, these solutions are numerically confirmed to be attractive, in contrast to the prediction of the Hawking's cosmic no-hair conjecture.
