Superfluidity  is  very  general  phenomenon  which  appears  in  a  variety  of  physical  systems. On a macroscopic level, superfluidity is usually modeled by a two - fluid hydrodynamic system where the fluid is formally divided  into  a  superfluid  and  normal  fluid  part. On  a  microscopic  level,  the  basic  ingredients  for superfluidity  are - at  least  in  principle - well  known:  The  spontaneous  breaking  of  a  continuous symmetry by a Bose - Einstein condensate together with the absence of elementary excitations, which could dissipate energy, allow for frictionless transport of the associated charge. However, the precise translation  of  microscopic  physics  into  the  hydrodynamic  description  remains an ongoing subject of research and is investigated in detail in this project. In addition repercussions on the phenomenology of compact stars are studied.
