我们研究了一种修正的宇宙动力学，其中宇宙由重子物质和一个复（经典）标量场组成。该场的相位分量被认定为轴子场，负责暗物质贡献，而其模遵循类似 $\lambda\phi^4$ 的理论，与主导的恒定能量密度相关，描述宇宙的暗能量成分。研究该复标量场的势项在其最大值附近时，自然会产生暗物质与暗能量之间的相互作用项。由此物理框架产生的宇宙学模型导致修正的 $\Lambda$CDM 动力学，其中暗物质贡献被轻微且单调地抑制。我们构建了与这种修正宇宙情景相关的有效跑动哈勃常数，并将此诊断工具与 Ia 型超新星潘特heon 样本的分箱数据进行比较。通过拟合过程，我们能够根据理论推测对数据给出令人满意的解释，该推测在统计上比 $\Lambda$CDM 模型更受青睐。
英文摘要
We investigate a modified cosmological dynamics in which the Universe is composed of baryonic matter and a complex (classical) scalar field. The phase component of this field is identified with the axion field, which accounts for the dark matter contribution, while its modulus follows a $λϕ^4$-like theory, associated with a dominant constant energy density and describing the dark energy component of the Universe. When the potential term of this complex scalar field is studied near its maximum, it naturally provides an interaction term between dark matter and dark energy. The cosmological model that emerges from this physical framework leads to a modified $Λ$CDM dynamics, in which the dark matter contribution is slightly and monotonically suppressed. We then construct the effective running Hubble constant associated with this revised cosmological scenario and we compare this diagnostic tool with the binned data of the Pantheon Sample of Type Ia Supernovae. As a result of the fitting procedure, we are able to provide a satisfactory interpretation of the data in terms of our theoretical conjecture that results statistically favored with respect to the $Λ$CDM model.
