    "abstract": "We propose a scheme to generate and detect various kinds of quantum\nentanglement in a spin-1 Bose-Einstein condensate. It is shown that substantial\nmany-particle entanglement can be generated directly in the spin-1 condensate\nby free dynamical evolution with a properly prepared initial state. The scheme\nalso provides a simple method to generate three-mode entanglement in the\nsecond-quantization picture and to detect the continuous variable type of\nentanglement between two effective modes in the spin-1 condensate.",
