Entanglement of two delocalised electrons
arXiv:cond-mat/0607680 · doi:10.1103/PhysRevA.74.010304
Abstract
Several convenient formulae for the entanglement of two indistinguishable delocalised spin-1/2 particles are introduced. This generalizes the standard formula for concurrence, valid only in the limit of localised or distinguishable particles. Several illustrative examples are given.
