This contribution is concerned with the investigation of non-equilibrium dynamics of superfluids in one spatial dimension enabled by the holographic description in terms of field theory in higher-dimensional black-hole-anti-de-Sitter spacetimes. We perform numerical solutions, applying the famous AdS/CFT duality of string and large-N field theory in a bottom-up fashion. Following the principles of holography this leads us to a way of calculating dynamics matched to the standard Gross-Pitaevskii-equation (GPE) based methods. The one-dimensional holographic superfluid is of peculiar fashion due to the renormalization needed on the boundary, which is due to the Weyl anomaly on the boundary not only consisting of the expected central charge. Of particular interest to us are topological defects, therefore we imprint solutions to the GPE, such as solitons, onto the superfluid and investigate how they evolve.
