Entropy meters and the entropy of non-extensive systems.
In our derivation of the second law of thermodynamics from the relation of adiabatic accessibility of equilibrium states, we stressed the importance of being able to scale a system's size without changing its intrinsic properties. This leaves open the question of defining the entropy of macroscopic, but unscalable systems, such as gravitating bodies or systems where surface effects are importan...
متن کاملExtensive Entropy Bounds
It is shown that, for systems in which the entropy is an extensive function of the energy and volume, the Bekenstein and the holographic entropy bounds predict new results. More explicitly, the Bekenstein entropy bound leads to the entropy of thermal radiation (the Unruh-Wald bound) and the spherical entropy bound implies the “causal entropy bound”. Surprisingly, the first bound shows a close r...
متن کاملA critique of non-extensive q-entropy for thermal statistics
Recently there have been numerous articles on a new relation between entropy and probability which is non-extensive, and which has an undetermined parameter q that depends on the nature of the thermodynamic system under consideration. For q = 1 this relation corresponds to the Boltzmann-Gibbs entropy, but for other values of q it is claimed that this relation leads to a formalism which is also ...
متن کاملOn the maximum entropy principle in non-extensive thermostatistics
It is possible to derive the maximum entropy principle from thermodynamic stability requirements. Using as a starting point the equilibrium probability distribution, currently used in non-extensive thermostatistics, it turns out that the relevant entropy function is Rényi’s α-entropy, and not Tsallis’ entropy.
متن کاملNon-extensive radiobiology
The expression of survival factors for radiation damaged cells is based on probabilistic assumptions and experimentally fitted for each tumor, radiation and conditions. Here we show how the simplest of these radiobiological models can be derived from the maximum entropy principle of the classical Boltzmann-Gibbs expression. We extend this derivation using the Tsallis entropy and a cutoff hypoth...
