论文摘要
在这项工作中，我们在$ {f（r，t）} $重力理论的背景下研究了通货膨胀。我们假设$ {f（r，t）} $的功能形式为$ r+16πgλt$，其中r是ricci标量，t是能量弹药张量的跟踪，$λ$是模型参数。宇宙学可观察的参数，例如标量光谱指数$ n_s $和张量表$ r $ $ r $，估计具有双孔电位。我们发现，对于$λ= 150美元，$ n_s $和$ r $与Planck 2018数据非常吻合。此外，考虑到Planckian的双孔潜力的真空期望值，我们观察到可允许的模型参数范围为$ 145 <λ<222 $，该模型与Planck 2018数据保持一致。
In this piece of work, we studied the inflation in the context of ${f(R,T)}$ theory of gravity. We assumed the functional form of ${f(R,T)}$ to be $R+ 16 πG λT$, where R is the Ricci scalar, T is the trace of the Energy-Momentum tensor and $λ$ is the model parameter. The cosmological observable parameters like scalar spectral index $n_s$ and tensor-to-scalar ratio $r$ are estimated for Double-Well potential. We found that for $λ= 150$, $n_s$ and $r$ are in good agreement with Planck 2018 data. Further, considering the vacuum expectation value in Double-Well potential to be Planckian, we observed the admissible range of model parameter to be $145 < λ< 222$ for which this model remains consistent with Planck 2018 data.
