| Abstract: | In this communication we consider the zero temperature properties of entanglement in free and interacting fermion systems
following Bogoliubov’s excitation approach. We investigate spin biparticle entanglement in BCS superconductor ground state
of electron gas and in EPS state of 3He atoms. The relation between pair-distribution functions and biparticle quantum entanglement is discussed. |
