New Tsallis holographic dark energy

Abstract Tsallis entropy is a generalization of the Boltzmann–Gibbs in statistical theory which uses parameter $$\delta $$ δ to measure deviation from standard scenario quantitatively. Using concepts and future event horizon, we construct new holographic dark energy model. The parameters c will be used characterize various aspects Analytical expressions for cosmological such as differential equation describing evolution effective density parameter, state deceleration are obtained. current model exhibits pure quintessence behaviour $$c>1$$ c > 1 , quintom $$c<1$$ < whereas $$\Lambda Λ CDM recovered $$c=1$$ = . To analyze thermal history universe, obtained expression found that $$z \approx 0.6$$ z ≈ 0.6 phase transits acceleration.
