Abstract
Bosonic quantum many-particle systems with long-range dipolar interactions display remarkable behaviour, such as the formation of quantum droplets and the emergence of supersolid phases with a rich spectrum of complex density-wave patterns. In particular, the anisotropic nature of dipole-dipole interactions highlights the role of fluctuations and, thereby, provides unique opportunities to scrutinize theoretical descriptions of quantum effects beyond simple meanfield pictures. Experiments on ultracold atoms with large magnetic dipoles and, more recently, the realization of ultracold polar molecules offer an excellent laboratory platform for exploring such phenomena and improving our understanding of long-range interacting quantum gases.
In this talk, we consider theoretically the formation of ordered phases of dipolar Bosons under conditions of recent experiments with magnetic atoms as well as polar molecules. Special emphasis will be placed on the detailed role of quantum fluctuations, confinement and geometry as well as temperature effects for the formation of ordered phases in extended systems of dipolar Bosons.
