  "abstract": "We develop a hybrid semiclassical method to study the dynamics of one dimensional systems in and out of equilibrium. Our method handles internal degrees of freedom completely quantum mechanically, and accounts efficiently for entanglement entropy generation by these. In non-equilibrium situations, we can follow time evolution up to timescales at which local thermalization occurs. As an application, we investigate the quench dynamics and phase fluctuations of a pair of tunnel coupled one dimensional Bose condensates described by the sine-Gordon model.",
