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
Longitudinal field (LF) muon-spin-relaxation measurements have been performed for polythiophene based polymers of regio-random poly(3-hexylthiophene-2,5-diyl) to elucidate the intra-and interchain hopping mechanisms. The LF dependent muon-spin depolarization rate indicates the occurrence of pronounc
