Entanglement entropy of the maximum geminal of the BCS ground state

Entanglement entropy of the maximum geminal of the BCS ground state

From the viewpoint of the Bose–Einstein condensation (BEC) of the fermion system, the maximum geminal of the second-order reduced density matrix of the superconducting state exactly corresponds to the Cooper pair. In this paper the entanglement entropy (EE) for the maximum geminal of the BCS ground...
