Many-body entanglement in fermion systems

We discuss a general bipartitelike representation and Schmidt decomposition of an arbitrary pure state of N indistinguishable fermions, based on states of M < N and ( N − M ) fermions. It is directly connected with the reduced M - and ( N − M ) -body density matrices (DMs), which have the sam...
