Ideal Gas provides Tsallis Distribution

Tamas Biro (Wigner Research Centre for Physics, Hungarian Academy of Sciences, Budapest)

The thermodynamical probability for an ideal gas having a given energy, E, and the conditional probability for a part of an ideal gas having another energy, E₁, are considered both in the traditional way and in a factorizing setting. The latter delivers the q-entropy formulas of Renyi and Tsallis. The factorizing quantity and the corresponding q-entropy is obtained for both types of probabilities. Finally perspectives for generalizations to systems with energy- or entropy-dependent heat capacity are discussed. (arxiv:1211.5284)
