Identical particles and entanglement
GianCarlo Ghirardi, Luca Marinatto
abstract: We review two general criteria for deciding whether a pure bipartite quantum
state describing a system of two identical particles is entangled or not. The
first one considers the possibility of attributing a complete set of objective
properties to each particle belonging to the composed system, while the second
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.
