Tsallis statistics with normalized q-expectation values is thermodynamically stable: illustrations
摘要
We present a study of both the ``Iterative Procedure'' and the `` transformation'', proposed by Tsallis et al (Physica A261, 534) to find the probabilities of a system to be in a state with energy , within the framework of a generalized statistical mechanics. Using stability and convexity arguments, we argue that the iterative procedure does not always provide the right temperature dependence of thermodynamic observables. In addition, we show how to get the correct answers from the `` transformation''. Our results provide an evidence that the Tsallis statistics with normalized q-expectation values is stable for all ranges of temperatures. We also show that the cut-off in the computation of probabilities is required to achieve the stable solutions.
