Bond-order-wave phase and quantum phase transitions in the one-dimensional extended Hubbard model

Abstract

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… (More)
