Note on Tsallis holographic dark energy / Zadeh, M. Abdollahi ; Sheykhi, A. ; Moradpour, H. ; Bamba, Kazuharu
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.

Dissipative properties and isothermal compressibility of hot and dense hadron gas using non-extensive statistics / Tiwari, Swatantra Kumar ; Tripathy, Sushanta ; Sahoo, Raghunath ; Kakati, Nilotpal
We evaluate the transport properties such as shear viscosity ( η ), bulk viscosity ( ζ ) and their ratios over entropy density ( s ) for hadronic matter using relativistic non-extensive Boltzmann transport equation (NBTE) in relaxation time approximation (RTA). [...]
