M-body Pure State Entanglement
Feng Pan, J. P. Draayer
Abstract
The simple entanglement of N-body N-particle pure states is extended to the more general M-body or M-body N-particle states where N≠ M. Some new features of the M-body N-particle pure states are discussed. An application of the measure to quantify quantum correlations in a Bose-Einstien condensate model is demonstrated.
