We study the phase diagram of the two-dimensional anisotropic next-nearest
neighbor Ising (ANNNI) model by comparing the time evolution of two distinct
spin configurations submitted to the same thermal noise. We clearly see several
dynamical transitions between ferromagnetic, paramagnetic, antiphase, and
floating phases. These dynamical transitions seem to occur rather close to the
transition lines determined previously in the literature.
