摘要：
By means of the quantum field theory (QFT) in the one-loop approximation, we consider the finite-size effect of the quantum fluctuation energy of a weakly interacting Bose–Einstein condensate (BEC) gas confined between two parallel plates of a three-dimensional rectangular. We find the repulsive Casimir-type force acts on the plates when either Zaremba boundary condition (BC) or anti-periodic BC is imposed. Our results are obtained in both grand canonical ensemble (GCE) and canonical ensemble (CE).
