What is it about?
What happens when you place quantum liquid, such as gaseous Bose-Einstein condensate or Helium-4 superfluid, into a free space, i.e., remove any trapping potentials including gravity? Will it expand, collapse or equilibrate? This article is about how to answer these questions, and predict outcome of future experiments in space.

Why is it important?
While trapless BEC's have been considered before, this research deals with a very general class of quantum liquids and gases. This class involves not only "polynomial" condensates but also "non-polynomial" ones, such as logarithmic. The latter are used for describing superfluid phase of Helium-4, for example, or guessing main properties of the physical vacuum (as defined in Superfluid Vacuum Theory).
Perspectives
This research is a part of a large project devoted to dense quantum liquids. It is supposed to set a theoretical network for further studies, both theoretical and experimental, with applications from space science to astrophysics. More details can be found on my webpage or Wikipedia.
