Extensive nonadditive entropy in quantum spin chains
We present details on a physical realization, in a many-body Hamiltonian system, of the abstract probabilistic structure recently exhibited by Gell-Mann, Sato and one of us (C.T.), that the nonadditive entropy Sq = k[1−Trρ̂q]/[q− 1] (ρ̂ ≡ density matrix; S1 = −kTrρ̂ ln ρ̂) can conform, for an anomalous value of q (i.e., q 6= 1), to the classical thermodynamical requirement for the entropy to be ext...
متن کاملExtensive Generalization of Statistical Mechanics Based on Incomplete Information Theory
Statistical mechanics is generalized on the basis of an additive information theory for incomplete probability distributions. The incomplete normalization is used to obtain generalized entropy . The concomitant incomplete statistical mechanics is applied to some physical systems in order to show the effect of the incompleteness of information. It is shown that this extensive generalized statist...
متن کاملFoundation of Equilibrium Statistical Mechanics Based on Generalized Entropy
The general mathematical formulation of the equilibrium statistical mechanics based on the generalized statistical entropy for the first and second thermodynamic potentials was given. The Tsallis and Boltzmann-Gibbs statistical entropies in the canonical and microcanonical ensembles were investigated as an example. It was shown that the statistical mechanics based on the Tsallis statistical ent...
متن کاملStatistical mechanics of ensemble learning
Within the context of learning a rule from examples, we study the general characteristics of learning with ensembles. The generalization performance achieved by a simple model ensemble of linear students is calculated exactly in the thermodynamic limit of a large number of input components and shows a surprisingly rich behavior. Our main findings are the following. For learning in large ensembl...
متن کاملThermodynamics, Statistical Mechanics and Entropy
The proper definition of thermodynamics and the thermodynamic entropy is discussed in the light of recent developments. The postulates for thermodynamics are examined critically, and some modifications are suggested to allow for the inclusion of long-range forces (within a system), inhomogeneous systems with non-extensive entropy, and systems that can have negative temperatures. Only the thermo...
