摘要
We briefly review some general aspects of Bose condensation and off-diagonal long range order in infinite bulk systems and then discuss to what extent these features might be manifested in finite systems with free surfaces such as droplets of liquid He-4 at low temperatures. We focus on the structure of the one-body density matrix and the macroscopic wave function in the surface region, and note the possibility of a surface condensate.
