Bose-Einstein Condensates: a model system for particle solvation?
  We propose that impurities in Bose-Einstein condensates can serve as a minimal laboratory system to explore the effects of quantum and thermal fluctuations on solvation. Specifically, we show that the role of quantum fluctuations in the formation of solvation shells and the breakdown of linear response theory can be explored in detail.
