DESCRIPTION:Speaker: Prof. Jeremy R. Armstrong\nhosted by Artem Volosniev (
 RG Serbyn)\nAbstract: We explore systems where an impurity potential is pl
 aced into a dipolar Bose-Einstein condensate (BEC). The dipole-impurity sy
 stem can exhibit attractive and repulsive interactions depending on the di
 rection as the dipole-dipole interaction is anisotropic. To analyze the sy
 stems\, we solve the modified Gross-Pitaevskii equation. Initial calculati
 ons were done in two spatial dimensions with a dipolar impurity. Results f
 or the impurity self-energy and the system density were obtained. In three
  dimensions\, the impurity is a repulsive asymmetric Gaussian potential. W
 ithout an impurity\, the system is elongated along one axis with the maxim
 um density predictably in the center. The impurity causes the central dens
 ity to fragment in different ways\, depending on the symmetry of the impur
 ity. These systems show an interesting interplay between the anisotropy of
  the medium with the anisotropy of the impurity.
