摘要

我们考虑类轴子粒子（ALP）模型来构建数值空间均匀各向异性Kantowski-Sachs宇宙学模型。我们研究了模型参数对标量场行为的影响。我们证明了类轴子标量场可以有不同的行为，在区间\(-1\leq\omega\leq 1\)有一个状态参数方程（EoS） \(\omega\)。

Axion-like Scalar Field in Kantowski–Sachs Background

We consider Axion-like particle (ALP) model to construct numerical spatially homogeneous anisotropic Kantowski–Sachs cosmological model. We investigate the impact of model’s parameters on the behavior of the scalar field. We demonstrate that axion-like scalar field could behave differently, having an equation of state parameter (EoS) \(\omega\) in the interval \(-1\leq\omega\leq 1\).

期刊介绍： Physics of Atomic Nuclei is a journal that covers experimental and theoretical studies of nuclear physics: nuclear structure, spectra, and properties; radiation, fission, and nuclear reactions induced by photons, leptons, hadrons, and nuclei; fundamental interactions and symmetries; hadrons (with light, strange, charm, and bottom quarks); particle collisions at high and superhigh energies; gauge and unified quantum field theories, quark models, supersymmetry and supergravity, astrophysics and cosmology.
