Nonadditive entropy for random quantum spin-S chains

arXiv:0912.3718 · doi:10.1016/j.physleta.2010.06.038

Abstract

We investigate the scaling of Tsallis entropy in disordered quantum spin-S chains. We show that an extensive scaling occurs for specific values of the entropic index. Those values depend only on the magnitude S of the spins, being directly related with the effective central charge associated with the model.
