| Popis: | In this work, we study the Tsallis holographic dark energy with Hubble horizon as IR cut-off with the energy density given by ρ Λ = 3 β 2 M p 2 H − 2 δ + 4 in f ( R , T ) theory. Considering a flat FRW Universe, we obtain the equation of state parameter guided by f ( R , T ) gravity. We investigate the correspondence between the tachyon, Dirac-Born-Infeld-essence, and the phantom scalar field models with the Tsallis holographic dark energy in the context of f ( R , T ) gravity. By equating the equation of state parameter in f ( R , T ) theory and ρ Λ with scalar field models, we reconstruct potentials and dynamics for these models for different Tsallis parameter δ . By analysis, we can show that for Tsallis holographic tachyon, Dirac-Born-Infeld-essence, and the phantom models, if the related model parameters fulfill some constraints, the accelerated expansion can be obtained in the framework of f ( R , T ) gravity. |
