Nonadditive entropy for random quantum spin- S chains
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 t...
