Computable Measures for the Entanglement of Indistinguishable Particles
arXiv:1211.1886 · doi:10.1103/PhysRevA.87.022327
Abstract
We discuss particle entanglement in systems of indistinguishable bosons and fermions, in finite Hilbert spaces, with focus on operational measures of quantum correlations. We show how to use von Neumann entropy, Negativity and entanglement witnesses in these cases, proving interesting relations. We obtain analytic expressions to quantify quantum correlations in homogeneous D-dimensional Hamiltonian models with certain symmetries.
