Abstract
We studied the miscibility of two dipolar quantum gases in the limit of zero tempera-ture. The system under study is composed of a mixture of two Bose gases with dominant dipolarinteraction in a two-dimensional harmonic confinement. The dipolar moments are all consideredto be perpendicular to the plane, turning the dipolar potential in a purely repulsive and isotropicmodel. Our analysis is carried out by using the diffusion Monte Carlo method, which allows for anexact solution to the many-body problem within some statistical noise. Our results show that themiscibility between the two species is rather constrained as a function of the relative dipolar momentsand masses of the two components. A narrow regime is predicted where both species mix and weintroduce an adimensional parameter whose value quite accurately predicts the miscibility of the twodipolar gases.
