The correlation functions of certain random antiferromagnetic spin-1/2 critical chains

João C. Getelina, José A. Hoyos

We study the spin-spin correlations in two distinct random critical XX spin-1/2 chain models via exact diagonalization. For the well-known case of uncorrelated random coupling cons…
