# Ground-state phase diagram of a dipolar condensate with quantum fluctuations

@article{Bisset2016GroundstatePD, title={Ground-state phase diagram of a dipolar condensate with quantum fluctuations}, author={Russell N. Bisset and R. Mark Wilson and D. Baillie and P Blair Blakie}, journal={Physical Review A}, year={2016}, volume={94}, pages={033619} }

We consider the ground state properties of a trapped dipolar condensate under the influence of quantum fluctuations. We show that this system can undergo a phase transition from a low density condensate state to a high density droplet state, which is stabilized by quantum fluctuations. The energetically favored state depends on the geometry of the confining potential, the number of atoms and the two-body interactions. We develop a simple variational ansatz and validate it against full numerical…
