Arifullin M.R., Berdinskiy V. L. NONLOCAL CORRELATIONS OF INDISTINGUISHABLE FERMIONS MULTISPIN STATESAny large system of N fermions, such as electrons with spin S = 1/2, the spin state of any particle are shown to be entangled with the other part of the system containing N-1 particle. However, the spin state of this electron is not entangled with any other particle, and spin state of any electron pair is not entangled. These properties of spin states manifest in the Einstein-Podolsky-Rosen as confirmation or violation of the Bell inequalities indicating the presence of non-local quantum spin correlations.Key words: quantum entanglement, density matrix, Pauli's principle, quantum correlations
