Query: Spin-1/2 transverse XX chain with a correlated disorder: dynamics of the
  transverse correlations   We examine numerically the dynamics of zz correlations in the spin-1/2
isotropic XY chain with random intersite coupling and on-site transverse field
that depends linearly on the neighbouring couplings (correlated off-diagonal
and diagonal disorder). We discuss the changes in the frequency profiles of zz
dynamic structure factor caused by disorder.
