摘要
Some equilibrium and nonequilibrium properties of the one-dimensional nearest-neighbor Ising ferromagnet that are grounded on nonadditive entropies are reviewed. First, we focus on the known fact that the nonadditive 熵 S-q for a special value of q, namely q(star )= root 37-6 similar or equal to 0.0828, yields entropic extensivity, thus satisfying the Legendre structure of classical 熱力學s, at the 量子 critical point of the spin-1/2 ferromagnetic Ising chain in the presence of an external transverse field. Then we address a well-known issue in 相變s, namely that, at the critical point, quantities such as the susceptibility and the Gr & uuml;neisen ratio diverge within Boltzmann-Gibbs 統計 mechanics (q=1). Moreover, we show that such thermo統計 quantities diverge for q>q(star), vanish for q.
