Self-gravitating Bose-Einstein-Condensates — Kris Schroven1, Betti Hartmann2, •Claus Lämmerzahl1, and Meike List1 — 1ZARM, University Bremen — 2Jacobs-University Bremen
Self-gravitating quantum systems serve as model for a variety of issues like Boson stars, gravitationally induced decoherence, or quasi-classical Einstein equations. Here we are considering self-gravitating Bose-Einstein-Condendates which are described by the Newton--Gross--Pitaevskii equation. We solve these equations for stationary spherically symmetric configurations and discuss the dependence of the solutions and their energy from the particle number and the value of the nonlinearity parameter. Also higher energy states will be presented. We close with an outlook describing possible issues which can be discussed within this formalism.
