A1 - Wilkens, Martin T1 - Bose-Einstein Condensation of two interacting particles N2 - We investigate the notion of Bose-Einstein condensation of interacting particles. The definition of the condensate is based on the existence of the dominant eigenvalue of the single-particle density matrix. The statistical properies and the characteristics temperature are computed exactly in the soluble models of two interacting atoms. Y1 - 2001 ER -
