Abstract: Microscopic bouncing balls, i.e., particles confined within a positive one-half-dimensional gravitational potential, display Bose–Einstein condensation (BEC) not only in the thermodynamic limit but also in the case of a finite number of particles, and the critical temperature with a finite number of particles is higher than that in the thermodynamic limit. This system is different from the one-dimensional harmonic potential one, for which the standard result indicates that the BEC is not possible unless the number of particles is finite.
