# Temperature-dependent density profiles of dipolar droplets

@article{Aybar2018TemperaturedependentDP, title={Temperature-dependent density profiles of dipolar droplets}, author={Enes Aybar and M. O. Oktel}, journal={Physical Review A}, year={2018} }

Recently, trapped dipolar gases were observed to form high density droplets in a regime where mean field theory predicts collapse. These droplets present a novel form of equilibrium where quantum fluctuations are critical for stability. So far, the effect of quantum fluctuations have only been considered at zero temperature through the local chemical potential arising from the Lee--Huang--Yang correction. Here, we extend the theory of dipolar droplets to non-zero temperatures using Hartree…
