$f(R,T)$重力场中沼泽地对应THDE的精粹场重建

Reconstruction of quintessence field for the THDE with swampland correspondence in $f(R,T)$ gravity

Umesh Kumar Sharma

摘要:

本文以Hubble视界为红外截止,构造了$f(R, T)$引力场中暗能量的Tsallis全息精粹模型。在平坦的FRW背景下,由于经典模型的能量密度与Tsallis全息密度之间的对应关系,使得经典场的动力学和势能得以重建。建议的THDE密度的哈勃视界红外截止值适用于两种特定情况:(i)THDE 1和(ii)THDE 2。我们已经重建的Tsallis全息精髓模型在区域$ω_Λ > -1$的EoS参数的情况下。此外,我们用沼泽地猜想分析了THDE模型的精华相,以描述宇宙的加速膨胀。

英文摘要:

In the present work, we construct the Tsallis holographic quintessence model of dark energy in $f(R, T)$ gravity with Hubble horizon as IR cut-off. In a flat FRW background, the correspondence among the energy density of the quintessence model with the Tsallis holographic density permits the reconstruction of the dynamics and the potentials for the quintessence field. The suggested Hubble horizon infrared cut-off for the THDE density acts for two specific cases: (i) THDE 1 and (ii) THDE 2. We have reconstructed the Tsallis holographic quintessence model in the region $ω_Λ > -1$ for the EoS parameter for both the cases. In addition, the quintessence phase of the THDE models is analyzed with swampland conjecture to describe the accelerated expansion of the Universe.
