Abstract
The realization of Bose-Einstein condensation (BEC) of dilute gases in stadium billiards due to the quantum chaos of Bogoliubov waves was analyzed. Investigations show that the Bogoliubov excitations were different from the single particle excitations in a noninteracting system. It was concluded that the statistical distribution of level spacing was unchanged by mapping the non-Hermitian Bogoliubov operator to a real symmetric matrix.
