Abstract:

A new theory of the interacting bose system is proposed. In contrast with the Bogoliubov theory, the condensate in the present theory is composed of the interacting dressed atoms and the total number of the dressed atoms is conserved. The second-order corrections to the ground-state energy and the excitation energy are evaluated to be found that the results in the present theory coincide with those obtained by Sunakawa et al. On the basis of this situation, it is shown that the present formalism is essentially equivalent to the theory of Sunakawa et al.
