Contribution

It demonstrates the impact of anisotropy on scalar field dynamics with non-minimal kinetic coupling across various potentials.

Findings

Anisotropy alters scalar field evolution compared to isotropic cases.

Different potentials respond uniquely to anisotropic backgrounds.

Explicit examples illustrate the changes in dynamics due to anisotropy.

Abstract

We consider a scalar field with a kinetic term non-minimally coupled to gravity in an anisotropic background. Various potentials for the scalar field are considered. By explicit examples, we show that how the anisotropy can change the dynamics of the scalar field compared with the isotropic background.
