    "abstract": "The definition of entanglement in identical-particle system is introduced.\nThe separability criterion in two-identical particle system is given. The\nphysical meaning of the definition is analysed. Applications to two-boson and\ntwo-fermion systems are made. It is found new entanglement and correlation\nphenomena in identical-boson systems exist, and they may have applications in\nthe field of quantum information.",
