The microscopic control available over cold atoms in optical lattices hasopened new opportunities to study the properties of quantum spin models. Whilea lot of attention is focussed on experimentally realizing ground or thermalstates via adiabatic loading, it would often be more straightforward to preparespecific simple product states and to probe the properties of interacting spinsby observing their dynamics. We explore this possibility for spin-1/2 andspin-1 models that can be realized with bosons in optical lattices, and whichexhibit \textit{XY}-ferromagnetic (or counterflow spin superfluid) phases. Weconsider the dynamics of initial spin-rotated states corresponding to amean-field version of the phases of interest. Using matrix product statemethods in one dimension, we compute both non-equilibrium dynamics andground/thermal states for these systems. We compare and contrast theirbehaviour in terms of correlation functions and induced spin currents, whichshould be directly observable with current experimental techniques. We findthat although spin correlations decay substantially at large distances and onlong timescales, for induction of spin currents, the rotated states behavesimilarly to the ground states on experimentally observable timescales.
