    "abstract": "We study the robustness, against the leakage of bosons, of wave functions of\ninteracting many bosons confined in a finite box, by deriving and analyzing a\ngeneral equation of motion for the reduced density operator. We identify a\nrobust wave function that remains a pure state, whereas other wave functions,\nsuch as the Bogoliubov\u0027s ground state and the ground state with a fixed number\nof bosons, evolve into mixed states. Although these states all have the\noff-diagonal long-range order, and almost the same energy densities, we argue\nthat only the robust state is realized as a macroscopic quantum state.",
