Recently various materials which are regarded as one-dimensional Ising chains have been synthesized and the nature of the phase transition attracts interests. We will discuss on the quantum phase transition of the transverse Ising model and its dynamical properties. In particular we will discuss time-dependence of magnetization under the sweeping magnetic field, where we found a kind of collective motion of magnetization which can be understood as a quantum version of the spinodal decomposition phenomena. We also discuss the effect of the size of spin "S" on the phase transition and also on the dynamics.
