Bond-order-wave phase and quantum phase transitions in the one-dimensional extended Hubbard model
We use a stochastic series-expansion quantum Monte Carlo method to study the phase diagram of the one-dimensional extended Hubbard model at half-filling for small to intermediate values of the on-site U and nearest-neighbor V repulsions. We confirm the existence of a novel, long-range-ordered bond-order-wave ~BOW! phase recently predicted by Nakamura @J. Phys. Soc. Jpn. 68, 3123 ~1999!# in a sm...
متن کاملEntanglement and quantum phase transition in the extended Hubbard model.
We study quantum entanglement in a one-dimensional correlated fermionic system. Our results show, for the first time, that entanglement can be used to identify quantum phase transitions in fermionic systems.
متن کاملEntanglement scaling in the one-dimensional Hubbard model at criticality.
We derive exact expressions for the local entanglement entropy epsilon in the ground state of the one-dimensional Hubbard model at a quantum phase transition driven by a change in magnetic field h or chemical potential mu. The leading divergences of delta epsilon/delta h and delta epsilon/delta mu are shown to be directly related to those of the zero-temperature spin and charge susceptibilities...
متن کاملQuantum Phase Transitions in an Integrable One-Dimensional Spin Model
A one-dimensional spin model, recently introduced and solved exactly, is studied. The solution, showing the appearance of a first-order quantum phase transition, is explicitly carried out and verified. Moreover, new results are found by generalizing the model to include anisotropy, thereby giving additional phases with both first-order and continuous quantum phase transitions. These transitions...
متن کاملBroken Symmetries in the One-Dimensional Extended Hubbard Model
The past two decades have witnessed the discoveries of several new classes of novel electronic materials. Ranging from conducting polymers through charge transfer solids and inorganic chain compounds to organic and high temperature superconductors, these materials have in common two important, unusual properties. First, their electronic structures are strongly anisotropic, in some cases (e.g., ...
