Abstract

The study of the compatibility of curvature-matter coupling gravity theory within the framework of swampland conjectures is explored in this manuscript. The de-sitter swampland conjecture is considered in relation to the inflationary solution generated by the curvature-matter coupling gravity. The slow-roll conditions are derived for the specific case of $f (R, L_{m}) = \frac{R}{2} + α {(L_{m})}^{n}$ model. The results show that the swampland conjectures are at odds with the slow-roll condition for curvature-matter coupling gravity theory. Therefore, it is concluded that the swampland conjectures and the curvature-matter coupling gravity, Specifically, $f (R, L_{m}) = \frac{R}{2} + α {(L_{m})}^{n}$ model appear to be inconsistent with each other within the context of an inflationary profile of curvature-matter coupling gravity theory.

通过沼泽猜想测试曲率-物质耦合重力

本文探讨了在沼泽猜想框架下曲率-物质耦合引力理论的相容性。考虑了由曲率-物质耦合引力产生的暴胀解的de-sitter沼泽猜想。对于f (R)的特殊情况，导出了慢滚条件。L m) = r2 + α （L m）N $f(\mathcal {R},\mathcal {L}_m)=\frac{\mathcal {R}}{2}+\alpha (\mathcal {L}_m)^n$模型。结果表明，沼泽猜想与曲率-物质耦合重力理论的慢滚条件不一致。因此，沼泽地猜想和曲率-物质耦合重力，即f (R)，L m) = r2 + α （L m）N $f(\mathcal {R},\mathcal {L}_m)=\frac{\mathcal {R}}{2}+\alpha (\mathcal {L}_m)^n$模型似乎在曲率-物质耦合引力理论的暴胀剖面中彼此不一致。

期刊介绍： The journal Fortschritte der Physik - Progress of Physics is a pure online Journal (since 2013). Fortschritte der Physik - Progress of Physics is devoted to the theoretical and experimental studies of fundamental constituents of matter and their interactions e. g. elementary particle physics, classical and quantum field theory, the theory of gravitation and cosmology, quantum information, thermodynamics and statistics, laser physics and nonlinear dynamics, including chaos and quantum chaos. Generally the papers are review articles with a detailed survey on relevant publications, but original papers of general interest are also published.
