    "abstract": "Entanglement in nonequilibrium systems is considered. A general definition\nfor entanglement measure is introduced, which can be applied for characterizing\nthe level of entanglement produced by arbitrary operators. Applying this\ndefinition to reduced density matrices makes it possible to measure the\nentanglement in nonequilibrium as well as in equilibrium statistical systems.\nAn example of a multimode Bose-Einstein condensate is discussed.",
