    "abstract": "For both cases with and without interactions, bipartite entanglement of\ntwo-fermions from a Fermi gas in a trap is investigated. We show how the\nentanglement depends on the locations of the two fermions and the total number\nof particles. Fermions at the verge of trap have longer entanglement distance\n(beyond it, the entanglement disappears) than those in the center. We derive a\nlower limitation to the average overlapping for two entangled fermions in the\nBCS ground state, it is shown to be $\\sqrt{Q/2M}$, a function of Cooper pair\nnumber $Q$ and total number of occupied energy levels $M$.",
