Far from equilibrium dynamics of an ultracold Bose gas, in one spatial dimension, is analysed with respect to topological excitations and compared to turbulent phenomena in two and three dimensions. A special focus is set on the single particle momentum distribution, which can be described within a statistical soliton model. The results give insight into the structure of (quasi-)stationary states of an ultracold Bose gas away from equilibrium.
