Description
The fascinating and complex world outside simplifying hypothesis such as ergodicity is hardly tractable, or plainly intractable, within the usual Boltzmann-­‐Gibbs frame, based on the well known additive Boltzmann-­ Gibbs-­von Neumann-Shannon entropy. Its generalization to nonadditive entropies and their consistent connections to thermodynamics, statistical mechanics, stochastic processes, central-­limit and large-­ deviation approaches, makes many of the usual methods successfully applicable to a wide class of both few-­ and many-­body complex systems. This path has shown to be fruitful in dealing -­‐ theoretically, experimentally, observationally and computationally -­‐ with many anomalous physical, astrophysical, cosmological (black holes), geophysical, chemical, financial, biological systems. The main concepts, some recent predictions, verifications, and applications (e.g., in the high-­energy experiments of the CMS, ATLAS, ALICE Collaborations at LHC/CERN), as well as nonlinear quantum-­mechanical extensions, will be presented.
