We investigate the Hamiltonian dynamics of two low-dimensional quantum spin systems in a random ÿeld, at the inÿnite-temperature limit: the XY chain and the two-leg XY ladder with interchain Ising interactions. We determine the longitudinal spin autocorrelation functions of the spin-1 2 XY chain and
