    "abstract": "We study pairwise quantum entanglement in systems of fermions itinerant in a\nlattice from a second-quantized perspective. Entanglement in the\ngrand-canonical ensemble is studied, both for energy eigenstates and for the\nthermal state. Relations between entanglement and superconducting correlations\nare discussed in a BCS-like model and for $\\eta$-pair superconductivity.",
