We study the dynamics of a two-dimensional system with complex conserved order parameter, following a deep quench. In accordance with a recent theoretical prediction, we observe an effective value of the dynamical exponent at late times of φ=0.245±0.010. While interesting dynamical effects were noticed in the study of the equal-time correlation functions, no evidence of multiscaling behavior was found. A correspondence between the quenched dynamics of this system in two dimensions and the dynamics of roughening of crystal-vapor interfaces is pointed out. We also study the dynamics in one dimension and find that φ0.18.
