    "abstract": "We investigate quantum entanglement between two (spin-1/2) fermions inside a\ncylindrical harmonic trap, making use of the von Neumann entropy for the\nreduced single particle density matrix as the pure state entanglement measure.\nWe explore the dependence of pair entanglement on the geometry and strength of\nthe trap and on the strength of the pairing interaction over the complete range\nof the effective BCS to BEC crossover. Our result elucidates an interesting\nconnection between our model system of two fermions and that of two interacting\nbosons.",
