摘要：

We show the existence of quantum states of the Heisenberg XY chain that closely follows the motion of the corresponding semiclassical ones, and whose evolution resembles the propagation of a shock wave in a fluid. These states are exact solutions of the Schrodinger equation of the XY model and their classical counterparts are simply domain walls or solitonlike solutions.
