Criteria for the entanglement of composite systems of identical particles
We identify a general criterion for detecting entanglement of pure bipartite
quantum states describing a system of two identical particles. Such a criterion
is based both on the consideration of the Slater-Schmidt number of the
fermionic and bosonic analog of the Schmidt decomposition and on the evaluation
of the von Neumann entropy of the one-particle reduced statistical operators.Comment: 8 pages, Late
