Quantum droplets in one-dimensional dipolar Bose-Einstein condensates — •Daniel Edler, Falk Wächtler, and Luis Santos — Institut für Theoretische Physik, Leibniz Universität Hannover, Germany

Recent experiments on dipolar Bose-Einstein condensates have reported the formation, due to quantum fluctuations, of a novel form of ultra-dilute stable droplets. We will show that in one-dimensional geometries these fluctuations lead to peculiar momentum dependence of the dipole-dipole interactions inducing an anomalous density dependence of the beyond-mean-field corrections. Further we will discussion the density distribution for different system parameters and the behaviour for included three-body losses.
