Abstract
The THDE (Tsallis HDE) model using an IR cut off as Ricci horizon has been investigated in the context of a flat Friedmann-Lemaı^tre-Robertson-Walker Universe by describing an accelerated expansion stage which Universe is experiencing. Evolution of Universe from decelerated (earlier) to the accelerated (current) phase exhibits by deceleration parameter (DP) attained in the model of THDE. The good behavior of cosmos is represented by Tsallis parameter δ and the EoS parameter’s values as phantom era (ωT<−1) and the quintessence era (ωT≥−1). Stability of the THDE model has been suggested by squared sound speed vs2. Additionally, for the THDE model the relation between phantom, quintessence and k-essence scalar fields has been analysed which helps to annotate the accelerated phase of the expanded Universe.
