Quantum disentangled liquid in the half-filled Hubbard model

Abstract:

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 that exhibit QDL behavior in the sense of Grover and Fisher [J. Stat. Mech. (2014) P1001010.1088/1742-5468/2014/10/P10010]. The states exhibiting the QDL property are atypical in the sense that wh...
