Abstract
It is shown that Bose-Einstein condensation occurs for an ideal gas in two spatial dimensions in the presence of one impurity which is described quant um mechanically in terms of a point-like vortex and a contact interaction. This model is exactly solvable and embodies as a special case the analogous problem in three spatial dimensions. (C) 2001 Elsevier Science B.V. All ri ghts reserved.
