Quantum disentangled liquid in the half-filled Hubbard model

We investigate the existence of quantum-disentangled liquid (QDL) states in the half-filled Hubbard model on bipartite lattices. In the one-dimensional case we employ a combination of integrability and strong-coupling expansion methods to argue that there are indeed finite energy-density eigenstates...
