We investigate the dynamics of BECs out of equilibrium in one spatial dimension by statistical simulations using the classical field equations. Special focus is set on the time evolution of the soliton formation and the characterisation of the quasi-steady solitonic state by measurements of characteristic quantities such as the density-density correlation, the spectrum of the one particle momentum distribution and the interference of condensates during the solitonic state. In particular we investigate the collision of multiple BECs released from an optical lattice and the interference of two coherent splitted one dimensional condensates. The results give insight into the dynamics and impacts of solitons in these systems.
