  We study theoretically and experimentally the behaviour of a strongly
confined dipolar Bose-Einstein condensate, in the regime of quantum-mechanical
stabilization by beyond-mean-field effects. Theoretically, we demonstrate that
self-organized striped ground states are predicted in the framework of the
extended Gross-Pitaevskii theory. Experimentally, by tilting the magnetic
dipoles we show that self-organized striped states can be generated, likely in
their metastable state. Matter-wave interference experiments with multiple
stripes show that there is no long-range off-diagonal order (global phase
coherence). We outline a parameter range where global phase coherence could be
established, thus paving the way towards the observation of supersolid states
in this system.
