    "abstract": "With Hubbard model, the entanglement scaling behavior in a two-dimensional\nitinerant system is investigated. It has been found that, on the two sides of\nthe critical point denoting an inherent quantum phase transition (QPT), the\nentanglement follows different scalings with the size just as an order\nparameter does. This fact reveals the subtle role played by the entanglement in\nQPT as a fungible physical resource.",
