We explore the effects of considering various
infrared (IR) cutoffs, including the particle horizon, the Ricci
horizon and the Granda–Oliveros (GO) cutoffs, on the properties
of Tsallis holographic dark energy (THDE) model,
proposed inspired by Tsallis generalized entropy formalism
(Tavayef et al. in Phys Lett B 781:195, 2018). Interestingly
enough, we find that for the particle horizon as IR cutoff, the
obtained THDE model can describe the late time accelerated
universe. This is in contrast to the usual HDE model which
cannot lead to an accelerated universe, if one considers the
particle horizon as the IR cutoff.We also investigate the cosmological
consequences of THDE under the assumption of a
mutual interaction between the dark sectors of the Universe.
It is shown that the evolution history of the Universe can
be described by these IR cutoffs and thus the current cosmic
acceleration can also be realized. The sound instability of the
THDE models for each cutoff are also explored, separately.
