摘要

在本文中,我们想要弄清楚在标量场和矢量场之间存在超重力驱动耦合的恒滚条件下,{\itk}-暴胀模型是否允许Bianchi型I度规作为其暴胀解,\(f^2(\phi)F_{\mu\nu}F^{\mu\nu}\)。结果表明,在这种情况下,一些新的各向异性暴胀解与幂律解一起出现。此外,与霍金宇宙无毛猜想的预测相反,这些解决方案在数值上被证实是有吸引力的。

Anisotropic Constant-roll \(k\)-inflation Model
In this paper, we would like to figure out whether a {\it 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, \(f^2(\phi)F_{\mu\nu}F^{\mu\nu}\). 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.
