摘要：

We show that the quantum many-body state of Bose-Einstein condensates consistent with the time-dependent Hartree-Fock-Bogoliubov (TDHFB) equations is a generalized coherent state. At zero temperature, the noncondensate density and the anomalous noncondensate correlation are not independent, allowing us to eliminate one of the three variables in the TDHFB.
