    "abstract": "We show how to detect entanglement with criteria built from simple two-body\ncorrelation terms. Since many natural Hamiltonians are sums of such correlation\nterms, our ideas can be used to detect entanglement by energy measurement. Our\ncriteria can straightforwardly be applied for detecting different forms of\nmultipartite entanglement in familiar spin models in thermal equilibrium.",
