Description
Summary:It has been recently shown that the Bekenstein entropy bound is not respected by the systems satisfying modified forms of the Heisenberg uncertainty principle (HUP) including the generalized and extended uncertainty principles, or even their combinations. On the other hand, the use of generalized entropies, which differ from the Bekenstein entropy, in describing gravity and related topics indicates different equipartition expressions compared to the usual one. In that way, the mathematical form of an equipartition theorem can be related to the algebraic expression of a particular entropy, different from the standard Bekenstein entropy, initially chosen to describe the black hole event horizon, see Abreu E. M. C. et al., Mod. Phys. Lett. A, 35 (2020) 2050266. Motivated by these works, we address three new uncertainty principles leading to recently introduced generalized entropies. In addition, the corresponding energy-time uncertainty relations and Unruh temperatures are also calculated. As a result, it seems that systems described by generalized entropies, such as those of Tsallis, do not necessarily meet HUP and may satisfy modified forms of HUP.
