Tsallis entropy links holographic dark energy to cosmic acceleration

This paper explores how Tsallis entropy, a generalization of standard entropy, can be applied in holographic dark energy models of cosmic acceleration. Using an ansatz-based approach, non-viscous, viscous, and Chaplygin gas scenarios are analyzed. Key properties relating to the phantom divide crossing and stability are studied. While viscosity and non-viscosity models exhibit instability, Chaplygin gas configurations demonstrate better stability, illuminating crucial connections between Tsallis entropy and cosmic expansion.
