摘要

The aforementioned experiments and results were limited to BECs comprising of local effective interactions. However, a range of exotic long-range interactions are possible. In particular, the creation of condensates with atoms possessing significant magnetic dipole moments affords a new opportunity to explore the interplay of magnetic effects with short-range interactions. In this chapter, we explore how dipolar interactions modify the elementary excitation spectrum and shape the properties of solitons and vortices in quantum gases, while also uncovering their role in the emergence of novel ultracold states of matter.
