论文摘要
我们在$ f（r，t）$重力（Harko等人，物理学修订版D 84，024020，2011）中研究标量场的行为，其中FRW FRW宇宙学模型的结构，其中$ r $和$ t $具有通常的含义。 FES的确定性解决方案已通过考虑比例因子$ s（t）= t^{m} e^{kt} $来解决，其中$ m $和$ k $是正常的。在这里，我们利用了三个正在进行的命令（$ h_ {0} = 73.8 $和$ q_ {0} = -0.73 $）从sne ia ia Union观察（Cunha，Phys。V.D 79，047301，2009））; （$ h_ {0} = 73.8 $和$ q_ {0} = -0.55 $）从类型IA Supernova（SNIA）观察（BAO）和（CMB）观察（Giostri等人，J。Cosmol。 （$ h_ {0} = 69.2 $和$ q_ {0} = -0.52）$（ohd+jla）观察（Yu等，Astrophys。J.856，3，2018）。我们已经测量并绘制了几个宇宙学参数，发现与宇宙的物理和运动学特性相比，这些发现是合适的，并且与正在进行的观察结果兼容。我们研究了Tachyon，K- essence和精髓的标量场模型之间的对应关系。我们的模型解释了FRW宇宙中标量场的潜力和动力学。重建的电势非常明智，并且具有缩放布置。随后，我们的研究支持最近的观察结果。
We investigate the behavior of the scalar field in $f (R, T )$ gravity (Harko et al., Phys. Rev. D 84, 024020, 2011) inside the structure of a flat FRW cosmological model, where $R$ and $T$ have their usual meaning. The deterministic solution of FEs has been settled by considering the scale factor $S(t) = t^{m}e^{kt}$, where $m$ and $k$ are positive constant. Here we utilize three ongoing imperatives ($H_{0}=73.8$ and $ q_{0}=-0.73$) from SNe Ia Union observation (Cunha, Phys. Rev. D 79, 047301, 2009); ($H_{0}=73.8$ and $ q_{0}=-0.55$) from Type Ia Supernova (SNIa) observation in joined with (BAO) and (CMB) observation (Giostri et al., J. Cosmol. Astropart. Phys. 03, 027, 2012); and ($H_{0}=69.2$ and $q_{0}=-0.52)$ from (OHD+JLA) observation (Yu et al., Astrophys. J. 856, 3, 2018). We have measured and graphed several cosmological parameters and found that these findings are appropriate in comparison with the universe's physical and kinematic properties and also compatible with ongoing observations. The correspondence between the scalar field models of tachyon, k-essence, and quintessence is investigated by us. Our model explains the potentials and the dynamics of the scalar fields in the FRW universe. The reconstructed potential is very sensible and has a scaling arrangement. Subsequently, our study supports recent observations.
